Removes naming conflict in get_shuffling. 
The variable name 'slot' in the for-loop in 'get_shuffling' conflicts with the get_shuffling argument name 'slot'. Renames 'slot' in for-loop to 'slot_num'.

Fixes typo in `sorted` function. 
In keeping with the rest of the code in this document we adhere to valid Python
where possible.

The custom comparator keyword argument for `sorted` is `key` so this commit
updates its usage when sorting validators by exit order.

Fix deserialize uint bounds logic

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:

Remove dangling `return` statement from spec function 
This function declares that it returns `None` and instead directly mutates the
state.

There is a dangling return statement that this commit deletes.

Fix a type error with units of wei when determining ejection balance. 
`EJECTION_BALANCE` is in units of ETH.

`state.validator_balances[index]` is in units of Gwei.

For the ejection computation to work as desired, we need to convert the
`EJECTION_BALANCE` constant from ETH to Gwei.

Change "justified hash" to "justified slot" 
There should be a correspondence here but referring to the slot is more
explicit, especially for those who are not as familiar with the
details of FFG finalization.

RANDAO hash chain and no stale shuffles 
* Make RANDAO into a hash chain (this makes it easy for applications to prove the intermediate RANDAO reveals).
* Include `state.slot` when shuffle to avoid stale shuffles with skip slots
