* Add support for deleting the trees
* Prune the trees
* Remove `Network` from `DiskWriteBatch`
Removing the `Network` from `DiskWriteBatch` makes it easy to
instantiate `DiskWriteBatch`es in `ZebraDb` that remove individual note
commitment trees.
The `Network` from `DiskWriteBatch` was used only for transparent
addresses, so the refactor isn't large. After removing it from
`DiskWriteBatch`, I passed it as a function argument instead. However,
we should simplify the parameter lists because at least two functions
have more than seven parameters now.
* Support individual tree removal in `ZebraDb`
* Refactor the tree removal task
* Prune old comments
* Remove redundant code
* Batch the removals
* delete ranges before relevant network upgrades
* moves prev_tree inits
* add iterator methods for reading note commitment trees
* Sets up skeleton of sapling pipeline
* Replaces .filter with .take_while
Fills in pipeline
Reuses zs_range_iter instead of repeating that code
Updates logic to stop at initial tip height
* uses std threads
* delete_range excludes end key
* fixes off by one bugs
* Log warning when a send fails
* Removes progress logs
* Log join errors instead of panicking
* Revert: Make the `db` field of `ZebraDb` private
* Move `delete_range_sapling_tree`
* Remove a redundant `else if` branch
Rationale:
The condition `n == 1` for the removed branch is true for a subset of
values of `n` in the preceding condition `n >= 1`.
