Merge pull request #209 from zcash/ecc-gadget-fixedpoints 
Store `Loaded` chip state in chip
 2021-02-26 04:24:28 +13:00
therealyingtong 4f17322c2d Allow Chip::load to return state that the Layouter will hold 
This enables chips that e.g. want to load multiple lookup tables into
the same columns to store state about where each table was layed out.
