Provide a low-level library


We'd like to use the logic analyzer to collect some long-term recordings. For this, we'd like to see a low-overhead library to access the basic functionality. No analysis or graphical features are required, only raw data.

This means, from C-Code, we want to:
* Configure the device, select analog and digital channels.
* Start sampling, and get a callback or similar when new samples are available. This shall run infinitely until stopped by user code.
* Available as source code so that it can be compiled to custom targets (ARM, x64, ...)
