- Update Rust toolchain to version 1.59.0 to satisfy the requirement of constant_time_eq v0.2.5, - Implement UncompressedEncoding for affine representations, - Add `paste` dependency at version 1.0.12 in order to give a specific struct for that representation for each of Pallas, Vesta.

The uncompressed representation (both coordinates are present in an affine point's representation) is useful in cases where one would want to avoid paying for the cost of a point decompression (e.g. public parameter caching).
pastedependency at version 1.0.12 in order to give a specific struct for that representation for each of Pallas, Vesta through a macro.Use case:
Point (de)serialization when caching public parameters (for e.g. a vector Pedersen commitments), where the deserialization can be prohibitively expensive if done with the compressed form of the points. The uncompressed points do not have that flaw.
