it's now possible to change most settings while scope-tui. Keybinds are
`v` for vectorscope/oscilloscope, `s` for scatter/line and `+/-` to
manage range.
in actual state, tool is pretty useful but not efficient or moddable in
its design. It's one single main and 5 crates, but draws a decent scope.
Requires pulseaudio and a fast terminal, but got this done in one night.
