* validate header mmr sizes, must grow for each block
* remove redundant height check
* fix tests after rebase
block specific TooHeavy error
* make sure header PMMR is init correctly based on header_head from db
* fix to ensure header PMMR is consistent with header_head in db on chain init
* change order of operations - validate header earlier
and avoid applying header to header PMMR before validation
as this potentially leaves the PMMR in a tricky state to rewind from

We have a method get which returns a Vec, it's used in cases when we can't implement FromLmdbBytes or Readable on a desired type, eg when both traits and type are external for the current crate. This approach requires an extra allocation of a Vec, this PR introduces a method which accepts desirialzer as closure, which allows to desrialize in place without an intermidiate heap allocation.
It's still possible to get a Vec if needed, just pass a Vec constructor to get_with.
We have to make an extra allocation per db get request because key generation function to_key takes Vec. Taking byte slice (AsRef<[u8]> to be precise) also simplifes the code a bit.
Currently Writable accepts trait Write as a type parameter but Readable
takes Read as a trait object, which is not symmetrical and also less performant. This PR changes Readable trait and all places where it's used
* Refactor SyncState
Method sync_error() retrun type was simplified.
update_txhashset_download() was made type safe, which eliminates a runtime enum variant's check, added an atomic status update
