* committee cache: prevent out-of-bounds access
In the case where we tried to access the committee of a shard that didn't have a committee in the
current epoch, we were accessing elements beyond the end of the shuffling vector and panicking! This
commit adds a check to make the failure safe and explicit.
* fix bug in get_indexed_attestation and simplify
There was a bug in our implementation of get_indexed_attestation whereby
incorrect "committee indices" were used to index into the custody bitfield. The
bug was only observable in the case where some bits of the custody bitfield were
set to 1. The implementation has been simplified to remove the bug, and a test
added.
