A fast and portable stack-based multi-precision integer library in pure Nim

Main focus:
  - Portability
    - 32 and 64 bit arch
    - ARM for usage on mobile phones
    - Additionally RISC-V and MIPS for open hardware and low power IoT devices.
  - Speed, library is carefully tuned to produce the best assembly given the current compilers.
    However, the library itself does not resort to assembly for portability.
  - No heap/dynamic allocation
  - Ethereum applications
    - Uint256/Int256 for Ethereum Virtual Machine usage.
    - Uint2048 for Ethereum Bloom filters
  - Ease of use:
    - Use traditional `+`, `-`, `+=`, etc operators like on native types
    - Representation of numbers in memory is the exact same as native types and endianness aware.
      - In practice that means that interfacing with binary blobs representing numbers from cryptographic    libraries can be done with a `cast` if it represents a Uint256, Uint512, Uint1024, Uint2048.
    - converting to and from Hex
    - converting to and from decimal strings
