Can't import the package with Matplotlib 3.6?

[russellxie]

Description

I was just trying to import the package an seeing the following error message. Using Matplotlib 3.6.0 and Python 3.9. It seems that the package is looking for a attribute in matplotlib.cm that does not exist.

Steps to reproduce

# import proplot

Expected behavior: [What you expected to happen]

Actual behavior:

### Proplot version
matplotlib 3.6.0
proplot 0.9.5 (installed through pip)
python 3.9.0

Found the answer in the other issue. I guess the package is only compatible with matplotlib 3.5 for now.

This is addressed in #309 -- haven't fixed dependency issues yet, but now installing proplot from scratch will at least enforce a compatible matplotlib version.
