Motivation

Looking at heap snapshots of a running lodestar node, the memory usage of shufflings stood out as larger than necessary.

Description

Replace number[] with Uint32Array for activeIndices, shuffling, and committees in the EpochShuffling.
This has two benefits: tighter packing of the data (TypedArray vs Object) AND data sharing between shuffling and committees.
The tradeoff is that only indices < 2 ^ 32 (4.2 billion) can be represented here, rather than indices < 2 ^ 53. In practice this is plenty and not an issue.
