add 8 segment displays to emulator

[borgdog]

initial setup of 8 segment displays for virtual emulator. I attempted to shape the crossing segments better, but it didn't seem to want to do that and I'm not sure how it fills between the points so may have something wrong. this does work but I have not extensively tested it for different sizes and bevels etc.

Linter is unhappy. Can you fix those?
