Support TF 2.15 (#101)

* Add TF=2.15 and TFP=0.23

* Exclude TF 2.15 with python 3.8

* Use older mypy version with python 3.7

* Use older mypy for py 37, 38, 39

* Exclude TF 2.15 with python 3.9

* Revert "Exclude TF 2.15 with python 3.9"

This reverts commit f9d95b5.

* Revert "Use older mypy for py 37, 38, 39"

This reverts commit 3e4f98c.

* Separate requirements for python 3.8

* Include python 3.9 in new requirements file

* Fix test by using sets directly with id

Behavior of tensorflow ObjectIdentitySet has change in 2.15,
resulting in the set equality comparing wrappers instead of
wrapped values. See tensorflow/tensorflow@bc28335.

* Also include intermediate TF versions

* Add exclude

* Add exclude

* Fix tfp versions
