Fix typo with initial generation of `latest_penalized_exit_balances`

The spec as written is not valid python -- the generator of the list
comprehension must be iterable.
It looks like the author simply meant to `range` over the intended length.
This commit fixes the missing `range` operator

Correct references to sig scheme in beacon spec.

BLS is the name of the signature scheme and BLS12-381 is the name of the

Fixes bugs with description of deposit verification.
...
1. The order of the `deposit_data` serialization does not match the current
Vyper contract. The description now matches that serialization.
2. The `deposit.merkle_tree_index` was not being used (at least explicitly) so
the text now reflects which inputs are to be used for which parameters in the
pseudocode spec that follows.
3. There seems to be a bug where we want the initial leaf to be the `hash` of
the `DepositData`, not the data itself. The text now reflects this requirement.

Add getter to Vyper contract for Merkle branches
...
Returns the Merkle branch for the leaf at index `index`. This getter provides
an alternative way for beacon chain proposers to access the Merkle tree of
deposits rather than being Ethereum 1.0 light clients. The method can be
called on a trusted Ethereum 1.0 archive node at specific past block numbers
to retrieve the Merkle branch needed to register a validator.

Fixes bug with Merkle proof branch selection
...
This code determines the order in which the next branch element and the
current value should be hashed to produce the parent node in the Merkle tree.
The existing code fails to verify branches constructed in the standard way.
This patch fixes the spec code so that it works properly by using an appropriate
parity calculation.
Example code here to illustrate it working:

* Added `activation_slot`, `exit_slot`, `penalized_slot`, `withdrawal_slot`, use these to determine if a validator is active
* Universal min activation/exit delay of 256 slots
* Min exit time of ~1 day, but penalization delays this to ~18 days
* Penalty calculation period of `[time penalized - 18 days, time penalized + 18 days]`; made the total penalties array fixed size and wraparound to make calculation more fine-grained
* Processes withdrawals in all epochs, not just dynasty-changing epochs
* Change `get_shuffling` function to take slot as argument
Not yet done:
* Removed `shard_committees` from the state

Add placeholder array in state for VDFs
...
Added `latest_vdf_outputs` in `state` initialised to an array of `ZERO_HASH` of length `LATEST_RANDAO_MIXES_LENGTH // EPOCH_LENGTH`. (There's one VDF output per epoch. The VDF input is the RANDAO mix at the epoch boundary.)
Further changes to activate VDFs (in a future phase):
* Add a new beacon "VDF output and proof" transaction, e.g. with `MAX_VDF_OUTPUT_AND_PROOF := 1`.
* Adjust the `MAX_SEED_LOOKAHEAD` constant, e.g. to `2**4 * EPOCH_LENGTH`. (The `2**4` parameter is essentially `A_max`.)
* Add a `process_vdf_output_and_proof` helper function in the per-block processing:
* Verify the VDF input hasn't already been processed (check the corresponding `state.latest_vdf_outputs` entry is not `ZERO_HASH`.)
* Verify the proof is correct, i.e. matches the VDF input and output
* Save the VDF output to `state.latest_vdf_outputs`
* In the per-epoch processing set the corresponding entry in `state.latest_vdf_outputs` to `ZERO_HASH`.
* Use a VDF output for the shuffling seed.

Changes to inactivity leak
...
* Fixes parameters and makes clear that the inactivity leak is on a per-epoch basis (before the leak was technically 64 times too weak as it was calculated per-slot but applied per-epoch)
* Adds a `// 2` to the inactivity leak to compensate for it being applied twice
* Changes how it is calculated (no inactivity leak for not being part of the head, only basic leak)
* Separates out early inclusion incentives into a separate incentive component rather than being multiplicative with everything else

Slight simplification. Only substantive change is that if the validator registry stays constant, we don't reshuffle 3 epochs after the last reshuffling (ie. before the reshufflings happened after 1, 2, 3, 4, 8, 16... epochs, now it's just 1, 2, 4, 8, 16...)

First pass cleanup of bls_verify.md
...
Misc cleanups:
* (typo) `highflag` => `highflag1`
* (typo) `lowflag = x = 0` => `lowflag == x == 0`
* Add structure and table of contents
* Describe more notation in words (e.g. `i`)
* Make sure flags are 1-bit
* Clarify and polish presentation
Example notation cleanups:
* `G1` => `id_G1` (to avoid confusing with the group G1)
* `field_modulus` => `q` (avoid using two names for same thing)
* `BLSVerify` => `bls_verify` (respect notation for functions in main document)
* `sig` => `signature` (avoid abbreviations as in main document)
TODO:
* Potentially describe `FQ2`, `b2`, `is_on_curve`, `multiply` in words
* Make the naming changes around `bls_verify` in the main document
* Fix any bugs introduced by the cleanup

* (cleanup) Polish and simplify presentation
* (bug fix) Fixed 2**34 value
* (bug fix) Replace epochs with slots to make the calculations work
