New protocol decoder: Aosong AM230x / DHT11

We're happy to announce that libsigrokdecode now supports the am230x protocol decoder.

This PD decodes the custom protocol of the Aosong AM230x and DHT11 temperature and humidity sensors.

A short description of the protocol is available on the respective wiki page, along with pointers to further reading.

There are also a bunch of teardown photos of these sensors, in case you were wondering what those look like inside. Turns out they usually use some ST STM8S (or other) microcontroller and measure temperature and humidity "directly" without further ICs. The exception being the Aosong AM2303 which actually uses a Dallas/Maxim DS18B20 (1-Wire) sensor for the measurement.

Thanks a lot to Johannes Roemer for contributing the decoder!
