a30568ff57 Add init function for BP statics
Considering they take 7 seconds to generate, thanks to #68, the ability 
to generate them at the start instead of on first BP is greatly 
appreciated.

Also performs minor cleanups regarding BPs.

023afaf7ce Bulletproofs+ (#70)
* 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

ee29f6d6d8 Implement Bulletproofs in Rust (#69)
* Initial attempt at Bulletproofs

I don't know why this doesn't work. The generators and hash_cache lines
up without issue. AFAICT, the inner product proof is valid as well, as
are all included formulas.

* Add yinvpow asserts

* Clean code

* Correct bad imports

* Fix the definition of TWO_N

Bulletproofs work now :D

* Tidy up a bit

* fmt + clippy

* Compile a variety of XMR dependencies with optimizations, even under dev

The Rust bulletproof implementation is 8% slower than C right now, under 
release. This is acceptable, even if suboptimal. Under debug, they take 
a quarter of a second to two seconds though, depending on the amount of 
outputs, which justifies this move.

* Remove unnecessary deref in BPs
