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

    - converting to and from raw byte BigInts (also called octet string in IETF specs)

    - converting to and from Hex

    - converting to and from decimal strings
