Merge pybadge and pyportal examples, and add wioterminal example

[sago35]

I will also try to make unicode font examples and so on at least work for both pyportal and wioterminal. The pybadge example has been merged into this PR as a preparation. And I've added the wioterminal example.

The following commands have been verified. I don't have pybadge so I am only checking build.

$ tinygo flash -size short -target wioterminal .\examples\pybadge
   code    data     bss |   flash     ram
  11104   32692    6332 |   43796   39024

$ tinygo flash -size short -target pyportal .\examples\pybadge
   code    data     bss |   flash     ram
  10728   32692    6332 |   43420   39024

$ tinygo build -o app.hex -size short -target pybadge .\examples\pybadge
   code    data     bss |   flash     ram
  11464   32692    6348 |   44156   39040

Another great contribution, thanks.

I'm ready to merge this, only issue I have, is that the three examples are inside "examples/pybadge" folder, not sure if a different name would be more appropiate, maybe "displays"?

[sago35]

That's certainly true. I don't think examples/pybadge is a good name for it either. I'm not good at coming up with names, so I'll rename it to examples/displays.

[sago35]

Rename done.

$ tinygo build -o app.hex -target wioterminal -size short .\examples\displays
   code    data     bss |   flash     ram

$ tinygo build -o app.hex -target pyportal -size short .\examples\displays
   code    data     bss |   flash     ram
  10728   32692    6332 |   43420   39024
