therealyingtong 7341996d2c gadget::ecc.rs: Add EccInstructions::constrain_equal() instruction. 
This allows us to constrain two points to be equal in value at the
gadget level.

therealyingtong e259bb3846 ecc::chip.rs: Use concrete pallas::Affine for Chip impl. 
The EccInstructions trait is still generic over C: CurveAffine;
however, the EccChip implementation is specific to the pasta
curves.
