feat(hermes): release v2 initial API (#1293)
The V2 API provide more functionality compared to the V1 such as supporting benchmark proofs for multiple ids. This change bumps the Hermes version to initiate a release and also fixes a couple of minor things: - Update build.rs to not panic on rebuilds - Remove an unused benchmarks file - Add all the V2 endpoints to docs
