* Improve tag map initialization and updating
Generalize tag map initialization and updating so that the tag map can
be loaded correctly prior to loading a `Corpus` with `spacy debug-data`
and `spacy train`.
* normalize provided tag map as necessary
* use the same method for initializing and updating the tag map
* Replace rather than update tag map
Replace rather than update tag map when loading a custom tag map.
Updating the tag map is problematic due to the sorted list of tag names
and the fact that the tag map will contain lingering/unwanted tags from
the default tag map.
* Update CLI scripts
* Reinitialize cache after loading new tag map
Reinitialize the cache with the right size after loading a new tag map.
* update `Morphologizer.begin_training` for use with `Example`
* make init and begin_training more consistent
* add `Morphology.normalize_features` to normalize outside of
`Morphology.add`
* make sure `get_loss` doesn't create unknown labels when the POS and
morph alignments differ
* Add morph to morphology in Doc.from_array
Add morphological analyses to morphology table in `Doc.from_array`.
* Use separate vocab in DocBin roundtrip test
* adding debug-model to print the internals for debugging purposes
* expend debug-model script with 4 stages: before, init, train, predict
* avoid enforcing to have a seed in the train script
* small fixes
* Update project CLI hashes, directories, skipping
* Improve clone success message
* Remove unused context args
* Move project-specific utils to project utils
The hashing/checksum functions may not end up being general-purpose functions and are more designed for the projects, so they shouldn't live in spacy.util
* Improve run help and add workflows
* Add note re: directory checksum speed
* Fix cloning from subdirectories and output messages
* Remove hard-coded dirs
