BitDecomposition for other Structs #56
Description
Implement BitDecomposition for more important structs, e.g., Scalar, Group and GroupVar in https://github.com/Manta-Network/manta-rs/blob/main/manta-crypto/src/arkworks/algebra.rs.
Will do this one once Todd merges his PR with several of the necessary migrations.
