Use max(uint64) for OOV lexeme rank (#5303)
* Use max(uint64) for OOV lexeme rank

* Add test for default OOV rank

* Revert back to thinc==7.4.0

Requiring the updated version of thinc was unnecessary.

* Define OOV_RANK in one place

Define OOV_RANK in one place in `util`.

* Fix formatting [ci skip]

* Switch to external definitions of max(uint64)

Switch to external defintions of max(uint64) and confirm that they are
equal.
