Dev/upgrade prophet 1.1

[jklaise]

Resolves #626.

Went straight to 1.1 as they have nice things:

• No dependency on pystan due to stopped development, the stan backend used now is cmdstanpy
• Wheels provided for all major platforms and Python versions so no installation woes, means we should be able to run Windows tests

I've tested also that the sole example notebooks works as expected.

These would both be great!

I've also updated the changelog (note removal of a couple of extraneous lines from previous releases).

Also note that I've manually checked the save/load functionality still works (we don't have a test for it, happy to add?).

When you say save/load functionality, what are you referring to? Saving and loading OutlierProphet via save_detector and load_detector?

Yup, that's the one.

Yup, that's the one.

There is actually one test for it in the legacy save/load tests (since outlier detectors are still saved in the legacy format):

https://github.com/SeldonIO/alibi-detect/blob/341af20c5e7e33ab46a206e1d2313c0465380085/alibi_detect/utils/tests/test_saving_legacy.py#L137-L141

We'll need to write a new one in saving/tests/test_saving.py once we've updated serialization for outlier detectors.
