  Description     : Fixed size 256-bit math library

 Fixed size 256-bit math library
 .
 This is a library specialized at replacing the big.Int library for math
 based on 256-bit types, used by both go-ethereum and erigon.
 .
 Current status
 .
  * As of 2020-03-18, uint256 wins over math/big in every single case,
    often with orders of magnitude.
  * And as of release 0.1.0, the uint256 library is alloc-free.
  * With the 1.0.0 release, it also has 100% test coverage.

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