now requires feature pulseaudio to build libpulse and pulse source. file
source is always included. the cli got reworked a little bit but I'm not
sure I like it this way, we'll see
Added CLI option to specify channel number, but I'm not sure it's really
working. Refactored AppConfig a little. Added threshold indication on
status bar. References and UI are separate settings and can be toggled
individually. At least 1 sample is always shown when discarding due to
triggering. Range and threshold are configured with arrow keys. Added
more colors to palette. Added ability to toggle braille mode. Fix: fully
write "fps" instead of cutting "s" out.
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.
