Arkworks Elliptic Curve utils overhaul (#1870)
- Removal of Arkworks unit tests. These tests were just testing the arkworks upstream implementation which should be assumed correct. This is not the place to test well known dependencies. - Removal of some over-engineering. We just store the calls to Arkworks in one file. Per-curve sources are not required. - Docs formatting --- I also took the opportunity to bump the `bandersnatch-vrfs` crate revision internally providing some new shiny stuff.
