Modular exponentiation (arbitrary output) and EIP-198 (#242)
* implement arbitrary precision modular exponentiation (prerequisite EIP-198)
* [modexp] implement exponentiation modulo 2ᵏ
* add inversion (mod 2ᵏ)
* [modexp] High-level wrapper for powmod with odd modulus
* [modexp] faster exponentiation (mod 2ᵏ) for even case and Euler's totient function odd case
* [modexp] implement general fast modular exponentiation
* Fix modular reduction with 64-bit modulus + fuzz powmod vs GMP
* add benchmark
* add EIP-198 support
* fixups following self review
* fix test paths
