  Description     : Fast Ethereum2.0 SSZ encoder/decoder

 The FastSSZ project in this repository is a combination of two things:
 a high performant low level library to work with SSZ encodings (root of
 this project) and the (sszgen (/sszgen)) code generator that generates
 the SSZ encodings for Go structs using the SSZ library. By combining
 both, this library achieves peak Go native performance and zero memory
 allocation. The repository uses as test the official Ethereum SSZ tests
 (spectests (/spectests/)) for the Consensus Spec data structures.
 .
 If you are only looking for the Consensus data structures and types
 with the SSZ support, it is recommended to use go-eth-consensus
 (https://github.com/umbracle/go-eth-consensus) instead, since it is
 already integrated with other parts of the Consensus stack, like the
 Beacon http API.

I want to package this library to unblock mev-boost, ITP bug #1107167.
