[TASK] Integrate non-rust MPC libraries using FFI

[drewstone]

Overview

Lots of great audited MPC libraries that we should investigate integrating since it will allow us to build a deeper library of gadgets out of the box. It will also create a great environment for benchmarking.

FFI

The FFI layer should be able to deal with protocols that don't leverage any networking. We would hook things up in a gadget implementation that generalizes across a wide variety of potential use cases (i.e. implement some trait and use protocol/ffi-tss-gadget)
