xmr: major protocol upgrade, CLSAG support added
- CLSAG signature scheme added
  - type hints added

xmr: optimize protocol, send only required data
  - real_out_additional_tx_keys contains only one element as nothing more is needed during signature
  - only src_entr.outputs[index] is HMACed and always present. Other outputs are present only if needed which reduces comm and CPU overhead.
  - getting rid of subaddresses dictionary (memory requirements), now subaddr indices are present per source entry so keys are computed when needed

xmr: prepare for permutation sending removal, specify index
  - specify source entry ordering index prior sorting by key images as original HMAC keys are generated based on these.
  - permutation checked just by valid HMACs, size of the set, key image sort order
  - sending permutation is now deprecated, will be removed in the following protocol versions
  - more strict state transition checks, guard strict check with respect to steps ordering
