Adjust stop bit condition in decode function

[ezrec]

Needed for when stop_bits is 1, instead of 2.

@ezrec Thanks; this change looks correct at first glance. I have not thought about this code in a long time.

Did you find the issue by inspection, or by some kind of concrete use? I would still expect minimodem to be fit for purpose more often than tynsel, but I would be happy to know if tynsel fit a need somewhere.

I would be happy to know if tynsel fit a need somewhere.

I’m using tynsel to get Wifi connection data to a ESP32 based wearable device. Tynsel was perfect for this, given its extremely low memory requirements.

The serial protocol I’m using for error correction expected 8-bit data, so I’m using 8N1 encoding, which highlighted the stop bit issue.

I’ve tried a few other audio receivers (quiet, ggwave) but tynsel fit my needs the best.

Thanks for all the work you put into it!
