all decoders: introduce a reset() method Move initialization code of protocol decoders from the constructor to a new reset() helper method. The libsigrokdecode backend could run this method several times to clear the decoder's internal state, before new data from another acquisition gets fed to decode() calls.
decoders: Rephrase condition-less .wait() calls (self documentation) Telling .wait() to "skip one sample" slightly obfuscates the intent of getting the next samples while no condition applies. Explicitly pass no condition arguments instead, to better reflect the purpose. Coincidently these .wait() calls will execute in slightly less expensive code paths in the common code.
