feat(xmr): implement bp+, refactor, code cleanup
...
- implement BulletProof plus verifier and prover
- use bulletproof exception to signalize proof generation failed and should be tried again. More robust, fixes bug that was not triggered yet (return tuple did not work properly in all situations)
- precomputed 2**i vector is removed as it can be easily computed
- BP code cleanup, minor optimizations, comments

xmr/bp: memory optimizations and improvements
...
- different approach to vector manipulation - more on the fly operations. Prepared for fully offloaded operations, BP on Trezor with constant memory.
- memory requirements reduced from (4MN + const) to (2MN + const)
- more raw methods to avoid unnecessary encoding/decoding
- chunking improved, chunk size set as a constant, changed from 64 to 32, missing pieces implemented to cover also BP 16
- proof_v8 support discontinued, old hardfork, not needed anymore
- get_exponent register clash fixed (for large vectors)
- reduced heap fragmentation by removing some temporary allocations
- hashing with len and offset to reduce heap fragmentation by creating a sliced arrays
- use to() wherever possible to avoid allocations and return of mutable private object
- global functions start with _ prefix, reduce import footprint
- use __slots__ in classes to minimize footprint
