flipper-logic_analyzer

I was missing a simple way of using Flipper as logic analyzer with e.g. PulseView, so I created a (prototype) plugin.

Just start the Flipper application and you will see smth like that for now:

Then start PulseView and add a new "Openbench Logic Sniffer (ols)" and select the second flipper serial port.

When arming, you can now look at the trace in PulseView.

Current state:

all 8 channels supported Channel 0 is C0, Channel 1 is C1, ... Channel 7 is A7
fixed sampling rate not supported (yet?)
if a trigger level is defined, no matter which one, the signals are captured as soon this signal changes
maximum capture rate unclear. didn't make any tests. guess in the 100kHz range
sample count capped to 16384 for now. didn't check what is possible using malloc()
only ONE SHOT currently supported. unknown reason. you have to close and reopen the capture window in PulseView (probably bug in PulseView?)
