Document svg-convert as a solution for cleaning up svgs

[bsutton]

I note in the readme you mention a couple of tools (scour, usvg) as options to clean up svg files.

We had a no. of svg files that contained css and the above tools were no help if resolving the issue.

We found the npm package svg-convert fixed the files. I thought it might be worth updating the readme to mention this tool:

svg-style-converter

To install the tool: sudo apt install npm sudo npm i svg-style-converter -g

To run the tool svg-convert

Sounds good, would you mind opening a PR with changes to the readme?
