* Consolidate GitHub CI actions, split out Monero
build now includes the specified Rust toolchain/components.
Added a test dependencies action which grabs Foundry and Monero.
Split the Monero v14 job into a matrixed job in its own workflow flow.
It's now only run when Monero has changes.
* Correct Monero unit/integration tests run timing
Additionally tests a feature-less Monero build.
Also removes a pointless Monero file, which already should have been
removed, causing this workflow to be triggered.
* Correct exclusion and paths
Updates to FROST should re-run the Monero tests to ensure it didn't
introduce API incompatibilities.
* Initial stab at Bulletproofs+
Does move around the existing Bulletproofs code, does still work as
expected.
* Make the Clsag RCTPrunable type work with BP and BP+
* Initial set of BP+ bug fixes
* Further bug fixes
* Remove RING_LEN as a constant
* Monero v16 TX support
Doesn't implement view tags, nor going back to v14, nor the updated BP
clawback logic.
* Support v14 and v16 at the same time
