conda packaging for Python 3.10

[mrakitin]

conda-forge/csxtools-feedstock#3 failed with a missing import. Need to resolve it on the package level and release a new version with the fix.

Falling back to matplotlib's imread(), which uses floats instead of integers. This may break your scripts.

This was resolved, and version 0.1.16 was built with Python 3.10 via conda-forge/csxtools-feedstock#5.

Currently building v0.1.18 from PyPI via conda-forge/csxtools-feedstock#7.
