Dusan Klinec	2658e253fa	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	5 years ago

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
