I think the readme needs cleanup, ideas:

• update fancy examples gif, have some things from different domains. We also have axes now so something that demonstrates that! Maybe the 3D line stack animation example?

• Cleanup examples section, just link to the gallery and docs. Move the stuff about embedding in a Qt app to the docs along with examples.

• Add a few points from docs on what fastplotlib is #480 to quickly "advertise" near the top of the readme about what fastplotlib is and what it's meant for/what it can do.

• There might be a way to make the "supported frameworks" section simpler, some form of "write once, run anywhere" to get across same code on jupyter and Qt/glfw desktop apps. Move fast from prototyping to real web apps or desktop apps.

• A section that lists the developers?
