Resolve #268 by adding a Zeroize to DigestTranscript which writes a full block
...
This is a 'better-than-nothing' attempt to invalidate its state.
Also replaces black_box features with usage of the rustversion crate.

Fix DigestTranscript to be secure
...
Collisions were possible depending on static label substrings. Now,
labels are prefixed by their length to prevent this from being possible.
All variables are also flagged by their type, preventing other potential
conflicts.

Use a transcript when generating the per-chain binding for a given set of keys
...
While it was fine as-is, as it only had one variable length property,
this is a bit more robust. Also binds the Curve ID, which should declare
differently even for just different basepoints, and therefore adds two
variable length properties (justifying the transcript).

Remove rng_seed's additional entropy
...
It was never used as we derive entropy via the other fields in the
transcript, and explicitly add fields directly as needed for entropy.
Also drops an unused crate and corrects a bug in FROST's Schnorr
implementation which used the Group's generator, instead of the Curve's.
Also updates the Monero crate's description.
