Issue with talon filter

[rugilemat]

Hi,

I have been trying to run talon filter on my database:

talon_filter_transcripts --db talon/database.db -a Hg38 --maxFracA 0.5 --minCount 1 --minDatasets 3 --o talon/talon_run.csv

And I'm getting an import error:

Traceback (most recent call last):
  File "/users/k19022845/.local/bin/talon_filter_transcripts", line 5, in <module>
    from talon.post.filter_talon_transcripts import main

ImportError: cannot import name 'is_categorical' from 'pandas.api.types' (/users/k19022845/.local/lib/python3.8/site-packages/pandas/api/types/__init__.py)

I previously had issues with numpy, so I installed it to be version 1.22.4.
