  Description     : Cryptographic Addition Chain Generation in Go

 addchain generates short addition chains for exponents of cryptographic
 interest with results rivaling the best hand-optimized chains. Intended
 as a building block in elliptic curve or other cryptographic code
 generators.
 .
  * Suite of algorithms from academic research: continued fractions,
    dictionary-based and Bos-Coster heuristics
  * Custom run-length techniques exploit structure of cryptographic
    exponents
    with excellent results on Solinas primes
  * Generic optimization methods eliminate redundant operations
  * Simple domain-specific language for addition chain computations
  * Command-line interface or library
  * Code generation and templated output support

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