Generating resources.rst from Google Spreadsheet

[glatosinski]

Fixes #189

This PR adds a script that takes XLSX file (or publicly available Google Spreadsheet ID) and generates resources.rst file from its contents. The sample spreadsheet that can be parsed by the script is available in https://docs.google.com/spreadsheets/d/1tOU0N0qMeDFjTz9NrGz_-PBikgu2x2gDHezy2SlE9dA/edit#gid=0

I would like to see a copy of the rendered rst file included in the readthedocs preview output so I can confirm it looks okay.

pandas seems a rather heavy dependency here? As pandas is a binary dependency it should probably also be in the environment.yml?

[glatosinski]

I used pandas to simplify accessing row fields. If pandas is too heavy I can replace it.

[glatosinski]

I put pandas in requirements.txt in case someone would like to install the required pip packages for skywater-pdk without using conda environment.

[glatosinski]

I also used pandas to read Google spreadsheet files directly from URL

I'm wondering if this should just be part of the sphinx documentation?

When does this tool run? Should it be run as part of building the documentation or as a scheduled github action (with the results committed to the repository)?

[glatosinski]

my idea was that this script should be executed like separately like rest of the generating scripts.

Here is the preview as for now: https://skywater-pdk--255.org.readthedocs.build/en/255/resources.html

BTW I think the data is starting to get there, but we need someone to make this page look beautiful :-) -- Maybe the rendered output should be a table rather than a list?
