Threshold Schnorr signs in 3ms, threshold ECDSA in 5s

This started as a side effect: I implemented FROST, CGGMP and DKLs23 in one codebase to understand them, and kept being surprised by how differently they cost. So I benchmarked everything I could get to build on one machine: my implementations, both Rust DKLs23 libraries, Binance's tss-lib, Taurus' CGGMP library and Zcash Foundation's frost crates.
