A fork of jet-proto-math. Helpful math utilities, used by PsyLend, and other PsyFi products.

Provides 192-bit and 128-bit integer libraries for dealing with values where decimal precision
is needed without the use of floats.

To run unit tests: `cargo test --release`
Note that `release` flag is important as we want to test production behavior where certain overflow checks in non-checked math is disabled.
