Chore: runs one round of package updates and updates rust-toolchain

[huitseeker]

unchanged: bitvec, criterion, ec-gpu, hex, rand, rand_xorshift, rust-gpu-tools, sha2, yastl

(criterion is probably safe to update though)

Are you running into problems? Those version updates all seem to be automatically covered by the version ranges we have. I don't really see a reason to upgrade.

This is mostly to pick up the rust-toolchain upgrade, but fair enough.
