Thanks! One question, and also, please remove the built files from the PR. They get built by jordi during release (there are actually 4 files that need to be built). |

Speeds up proving by caching zkey getCurve call when reading headers and avoiding double calls in grothProve. On a smallish circuit (https://github.com/nalinbhardwaj/snarky-sudoku) this amounts to a ~30% reduction, which is pretty significant IMO:
Before:
~4 seconds runtime
After:
~3 seconds runtime
