Fix failing tests and do general maintance (#938)

* Skip tests for unreleased detectors and ensemble detectors

* Set `weights_only=False` in stateful-detector load

* Bound seed values between 0 and 2**32 - 1 to prevent numpy error

* Set `use_safetensors=False` in tensorflow embedding model in order to fix tf/huggingface incompatibility

* Free up space prior to running CI installs

* Fix `progbar` error with numpy arrays

* Remove all from `optional_deps` tests in CI

* Ignore unreleased outlier detector files when running mypy and flake8

* Update licenses

* Remove unreleased OD api docs

* Add comment about bounds in set_seed function doc string
