libsigrok Toy Decoder

This is a very minimal example for writing your own quick-and-dirty decoder that you can use in PulseView.

This decoder displays annotations for a signal that's made up of 1 ms units. It annotates from one signal edge to another, without regard for time. If you want to handle the actual units of time, more logic is required and that's left as an exercise for the reader.
