PyArrow upgrade to 14.0.1

[cshaley]

Issue: #862

Notes:

• upgraded pyarrow to 14.0.1
• added fsspec because 2 unit tests did not work without it
• increased evidently version so we get a new version published with new pyarrow.

Questions:

• do I need to increase the pyarrow version in the integrations folders' requirements.txt file?
• do you like pinning with pyarrow<15? Or want a different pin?

Hi @cshaley ,
Thank you a lot for addressing this issue and making the contribution!

I apologise for the late reply. We discussed internally how to address this issue in a best way, and we were choosing between the approach you suggested and getting rid of pyarrow as dependency.

At this point, we decided to remove pyarrow from the dependencies and because of this we won't merge this PR.

I hope it solves the issue for you (the update is available in Evidently 0.4.11)
