doxygen ci

[tdealtry]

Automatically builds & pushes HTML to https://mach3-software.github.io/MaCh3/index.html when there are changes to develop

Note that this doesn't give version history for the documentation - it simply stores the latest doxygen build. This feature could be added in a future PR, if there is a need for it

Do let me know if anything looks odd

• one thing I noticed is the MaCh3 logo in the page header is way too big... I will fix that
• I'm not compiling/uploading the PDF, since I personally don't think this is required. Do shout if you disagree

Cheers, this looks lovely

I agree agree logo is too big...

Could you add link to github.io somewhere in readme? For example around here https://github.com/mach3-software/MaCh3/blob/761cdc168663a6cfe659e4e3bab0d939bf715273/README.md?plain=1#L9
