This is a companion PR to https://github.com/python-graphblas/python-graphblas/pull/432

I copied the logo from that PR and manually modified it.

Okay, I think the logo should be fixed now if you'd like to take a look to verify.

nope looks the same

Dope! Thanks for checking. Jim and I have learned that the font looks very different on different systems (Windows, Mac, Android, etc). So, I think @jim22k is going to convert all the svg logos to PNGs (Jim, don't forget to minimize the PNGs--such as from https://compresspng.com/ and https://tinypng.com/ --to improve page load times!).

[jim22k]

I switched from svg to png. This bumps the logo size from 1k to 35k, but I think it's worth it to avoid the need to grab fonts from the local machine, which leads to different looks and widths. PNG will always be consistent.

Thanks for converting the svg font to paths @jim22k. I minified the svg (that you converted the font into paths) with https://vecta.io/nano and deleted the png, b/c the svg looks better.

I think this is good to go in :tada:

Now let's do the same for the svgs in python-graphblas :)
