* add parameter fast_validation to the api
* arg `verify-chain` on node client
* arg verify chain + read_timeout parameter
* change timeout to 2hours
* update with tromp review
* 2nd comment from tromp
* replace bitvec with more efficient bitpack algorithm
* optimise proof_unpack_len
* move proof pack length calculation
* small refactor
* first pass attempt at not deserializing proof nonces in difficulty iter
* another 10 seconds gained by not deserialising the proof from the difficulty iterator
* add new deser parameters to tests where needed
* add skip_proof variants to store
* remove hash from difficulty iterator struct, rename HeaderInfo to HeaderDifficultyInfo

* 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
* refactor output to have internal output identifier
refactor to use AsRef for output identifier
make the output MMR explicit in terms of output identifiers
* put the serde deser back for rangeproof
* add json test for transactions
* Node API: don't error on missing output
* Propagate errors from get_output*
* Rename is_unspent and small refactor
* Forgot to rename function in tests
* Change Batch get_output_pos_height type signature
* Node API v2
* Update gitignore
* Add get_pmmr_indices method
* Add Foreign and Owner API each one with specific secret
* Fix failing tests
* Revert to 'Option<u64>'
* Kernel lookup api
* Min and max height parameters, scan backwards
* Return null instead of 404 if kernel not found
* Return TxKernel instead of TxKernelPrintable
* Update description of KernelHandler
