Ines Montani cf65a80f36 Refactor lemmatizer and data table integration (#4353)
* Move test

* Allow default in Lookups.get_table

* Start with blank tables in Lookups.from_bytes

* Refactor lemmatizer to hold instance of Lookups

* Get lookups table within the lemmatization methods to make sure it references the correct table (even if the table was replaced or modified, e.g. when loading a model from disk)
* Deprecate other arguments on Lemmatizer.__init__ and expect Lookups for consistency
* Remove old and unsupported Lemmatizer.load classmethod
* Refactor language-specific lemmatizers to inherit as much as possible from base class and override only what they need

* Update tests and docs

* Fix more tests

* Fix lemmatizer

* Upgrade pytest to try and fix weird CI errors

* Try pytest 4.6.5

Ines Montani f2c8b1e362 Simplify lookup hashing
Just use get_string_id, which already does everything ensure_hash was supposed to do

💫 Adjust Table API and add docs (#4289)
* Adjust Table API and add docs

* Add attributes and update description [ci skip]

* Use strings.get_string_id instead of hash_string

* Fix table method calls

* Make orth arg in Lemmatizer.lookup optional

Fall back to string, which is now handled by Table.__contains__ out-of-the-box

* Fix method name

* Auto-format

* Update test_lookups.py

* Update test_serialize_vocab_strings.py

* Lookups / Tables now work

This implements the stubs in the Lookups/Table classes. Currently this
is in Cython but with no type declarations, so that could be improved.

* Add lookups to setup.py

* Actually add lookups pyx

The previous commit added the old py file...

* Lookups work-in-progress

* Move from pyx back to py

* Add string based lookups, fix serialization

* Update tests, language/lemmatizer to work with string lookups

There are some outstanding issues here:

- a pickling-related test fails due to the bloom filter
- some custom lemmatizers (fr/nl at least) have issues

More generally, there's a question of how to deal with the case where
you have a string but want to use the lookup table. Currently the table
allows access by string or id, but that's getting pretty awkward.

* Change lemmatizer lookup method to pass (orth, string)

* Fix token lookup

* Fix French lookup

* Fix lt lemmatizer test

* Fix Dutch lemmatizer

* Fix lemmatizer lookup test

This was using a normal dict instead of a Table, so checks for the
string instead of an integer key failed.

* Make uk/nl/ru lemmatizer lookup methods consistent

The mentioned tokenizers all have their own implementation of the
`lookup` method, which accesses a `Lookups` table. The way that was
called in `token.pyx` was changed so this should be updated to have the
same arguments as `lookup` in `lemmatizer.py` (specificially (orth/id,
string)).

Prior to this change tests weren't failing, but there would probably be
issues with normal use of a model. More tests should proably be added.

Additionally, the language-specific `lookup` implementations seem like
they might not be needed, since they handle things like lower-casing
that aren't actually language specific.

* Make recently added Greek method compatible

* Remove redundant class/method

Leftovers from a merge not cleaned up adequately.
