#6087 introduced a subtle change to `nim-web3` resulting in `Gwei` to be
serialized differently than before. Using a `distinct` type for `Gwei`
improves type safety and avoids such problems in the future.
Annotate the `research` and `test` files for which no further changes
are needed to successfully compile them, to not interfere with periodic
tasks such as spec reference bumps.
Suite names were not being used because `test` has to have access to it
during instantiation - this PR cleans things up a little while at the
same time upgrading unittest2.
This PR removes a few hundred thousand temporary seq allocations during
state transition - in particular, the flag seq was allocated per
validator while committees are computed per attestation.
