Tweak inclusion delay rewards and set BASE_REWARD_FACTOR
...
Substantive changes:
1) Split the inclusion delay reward between attester and proposer to add up to at most one base reward. This is analogous to the reward logic in `slash_validator`, and makes the `BASE_REWARDS_PER_EPOCH` constant include proposer rewards.
2) Double `BASE_REWARD_FACTOR` to 2^6 (addressing item 4 in #1054 ). When the total effective balance is 2^17 ETH then maximum annual issuance is a bit below 2^21 ETH. Maximum annual issuance happens when a) all validators make perfect attestations (matching source, target, head, as well as consistent crosslink data), b) all attestations are included as fast as possible (in particular, no skip blocks), and c) there are no slashings.
```python
BASE_REWARD_FACTOR = 2**6
SLOTS_PER_EPOCH = 2**6
SECONDS_PER_SLOT = 6
BASE_REWARDS_PER_EPOCH = 5
GWEI_PER_ETH = 10**9
MAX_TOTAL_EFFECTIVE_BALANCE = 2**27 * GWEI_PER_ETH
TARGET_MAX_ISSUANCE = 2**21 * GWEI_PER_ETH
def integer_squareroot(n: int) -> int:
"""
The largest integer ``x`` such that ``x**2`` is less than or equal to ``n``.
"""
assert n >= 0
x = n
y = (x + 1) // 2
while y < x:
x = y
y = (x + n // x) // 2
return x
MAX_REWARDS_PER_EPOCH = MAX_TOTAL_EFFECTIVE_BALANCE * BASE_REWARD_FACTOR // integer_squareroot(MAX_TOTAL_EFFECTIVE_BALANCE) // BASE_REWARDS_PER_EPOCH
EPOCHS_PER_YEAR = 365.25*24*60*60 / (SECONDS_PER_SLOT * SLOTS_PER_EPOCH)
MAX_REWARDS_PER_YEAR = EPOCHS_PER_YEAR * MAX_REWARDS_PER_EPOCH * BASE_REWARDS_PER_EPOCH
print(MAX_REWARDS_PER_YEAR / TARGET_MAX_ISSUANCE)
```

Avoid divisions by zero
...
Possible fix to avoid four cases of divisions by zero:
* `return state.validator_registry[index].effective_balance // adjusted_quotient // BASE_REWARDS_PER_EPOCH`
* `rewards[index] += get_base_reward(state, index) * attesting_balance // total_balance`
* `validator.effective_balance * min(total_penalties * 3, total_balance) // total_balance`
* `rewards[index] += base_reward * attesting_balance // committee_balance`

Clean up verify_indexed_attestation
...
Cosmetic changes:
* Add 4 lines of comments (now every statement has a comment)
* Avoid unnecessary `assert` (the end goal for me is for `assert`s to be exclusive to the operation processing helpers).
* Merge `return`s into one (increase readability, reduce verbosity)
* Use shorter-named `bit_0_indices` and `bit_1_indices` helper variables
Substantive change:
* Remove the condition that `len(0_indices) + len(1_indices) > 0`. This condition is redundant in the context of `process_attester_slashing` because of `slashed_any`. It is largely artificial in `process_attestation` where validators are incentivised to maximise new attestations.

Attestation committee refactor
...
* Remove `get_crosslink_committees_at_slot` (that function's ugly man...)
* Make the "base" that everything works off instead be `get_crosslink_committee`
* Attestations store epoch, start shard and shard, no longer slot (slot can be calculated from the other three)
* Retaining start shard in attestations allows `get_attesting_indices` to peek much further back into the past, making it useful for slashings (Phase 1)
* Some two-layer-deep nested loops become one-layer-deep loops

Fix two effective_balance bugs
...
* Initialisation bug: initial `effective_balance` be not greater than `MAX_EFFECTIVE_BALANCE`
* Hysteresis bug: do not prevent `effective_balance` to go from `MAX_EFFECTIVE_BALANCE - 1` to `MAX_EFFECTIVE_BALANCE`
