Change to new theme

Signed-off-by: Daniel Lim Wee Soong [email protected]

Update docs/requirements.txt to use the new SymbiFlow theme, and update conf.py to remove extra options and use the correct name for the primary and accent colors.

Also update primary color to green to improve readability. (Any comments on this?)

• Tests pass
• Appropriate changes to README are included in PR

We have lost a bit of functionality with this change.

• The green colors have changed.
• The links in the headers.
• The expandable left hand headers.

I was trying out the darker green color as I think it is more readable, changed it back to the light green that was used before.

Also, I realized I missed out the Github and skywater links as you mentioned, and have added them already.

Currently the theme does not support expanding the headers on the left bar. I can work on adding them.

Modified the theme to allow expanding of the toc links. f4pga/sphinx_f4pga_theme#8

There are still some follow on work which needs to be investigated;

• Current page is not expanded in left panel table of content f4pga/sphinx_f4pga_theme#10
• Links with subpages no longer clickable on the left hand side panel f4pga/sphinx_f4pga_theme#11
