ratio library

Header-only, constexpr library providing exact representation for rational numbers.

Relative to std::ratio:

1. Uses constexpr instead of creating new types. This means it can be used seamlessly at runtime.
2. Supports a few more arithmetic operations, for example exponentiation to integer powers.
3. Provides concept support (with c++20)
4. Requires modern (c++17) support to achieve this
