The prior workflow (now deleted) required manually specifying the packages to check and only checked the package could compile under the stated MSRV. It didn't verify it was actually the _minimum_ supported Rust version. The new version finds the MSRV from scratch to check if the stated MSRV aligns. Updates stated MSRVs accordingly. Also removes many explicit dependencies from secq256k1 for their re-exports via k256. Not directly relevant, just part of tidying up all the `toml`s.
embedwards25519
A curve defined over the Ed25519 scalar field.
This curve was found via tevador's script for finding curves (specifically, curve cycles), modified to search for curves whose field is the Ed25519 scalar field (not the Ed25519 field).
p = 0x1000000000000000000000000000000014def9dea2f79cd65812631a5cf5d3ed

D = -420435
y^2 = x^3 - 3*x + 4188043517836764736459661287169077812555441231147410753119540549773825148767
The embedding degree is (q-1)/2.
This curve should not be used with single-coordinate ladders, and points should always be represented in a compressed form (preventing receiving off-curve points).
