There is currently a noticable flicker on the screen with my breadboarded prototype. Possible causes include:

• Draw loop should really be happening asynchronously. Not likely to be the the cause, since the flicker happens even when there's nothing else going on in the main loop. Also not really something i can change until circuitpython adds async support.
• Not enough voltage on the higher voltage pins.
• Several VFD resources online mention using alternating current, but it's not clear if they're recommending it for the lower voltage pins or the higher voltage pins.
• Some important electronics components are missing from my circuit because i don't really know what i'm doing.

AC

• Cause of flickers is investigated and resolved if possible.

The readme file needs to be updated with some useful diagrams and better explanations of how to use the library.

AC

• "How do they work?" is expanded and diagrams added
• "Wiring" is expanded and diagrams added
• "How do i use this library?" is expanded
