Adding timestamps to Recorded Signals and ProtocolAnalyzer messages
Adding timestamps to messages generated in ProtocolSniffer

Before this PR, signals and messages interpreted by protocol analyzer, had no real timestamps; just some relative time measurements between each messages in signal. Now timestamps are absolute and are saved into proto.xml files correctly for future reference.

@jpacov could you please sign the CLA? Probably it wants that again due to the force-push or something.

It would be nice to add some unit-tests or update existing ones to verify the new timestamps work as expected. I do not have an SDR here to test recording/Protocol Sniffer so if someone from the community could test this would be appreciated.

So that _ppseq_to_bits populates bit_sample_pos array and we are able to calculate more accurate timestamps using bit sample position.

@jopohl I tested more extensively the timestamps, and made some changes and small fixes. I also added some small unit tests for the ProtocolSniffer as you requested. Let me know if that is enough.

@jpacov sorry for late reply, could you please pull in latest changes from master? I just updated the CI to support more recent Python versions and like to ensure your changes are compatible.

With this MR, timestamps for decoded messages are calculated correctly (useful when exporting decoded messages).
Working for signals recorded on Record signal window, Sniff protocol window and for signals derivated from other signals (e.g. after filtering a signal).

Here an example:
