* wip - "reset_head" via owner api functionality
* jsonrpc pass hash in as a string
* sort of works
* not a reorg if we simply accept several blocks at once
* remember to reset header MMR separately
as it is readonly when interacting with txhashset extension
* basic client integration
needs error handling etc.
* reset sync status when reset chain head
* track "denylist" (todo) and validate headers against this via the ctx
* track denylist (header hashes) in chain itself
* header denylist in play
* expose invalidateheader as client cmd
* rework reset_chain_head - rewind txhashset then header MMR
* fix for comparing scaled vs unscaled difficulty
fix mix use of scaled and unscaled, add additional comments to clarify which values are which
improved consistency - scaled and unscaled difficulty
* combine from_proof_unscaled() and to_unscaled_difficulty{}
* code review - rust syntax
* track sync_head on header_sync sync status
follow header fork as appropriate
* track highest_diff alongside highest_height on HeaderSync status
* cleanup
* not not
* invalid range proof test
* create output with 1 million grin
* Move `output_negative` into `tests/`
So it cannot be called from outside of tests!
* Verify InvalidBlockProof & InvalidRangeProof types
