Exception in radae_rxe.py during decode of freedv-gui recording

[tmiw]

I just tried to play a file someone sent to the digitalvoice list through freedv-gui and got the following exception on the console:

Traceback (most recent call last):

This is using commit 98cf722 (which is the latest in dr-cport but I don't see anything checked into main since then). I can also duplicate using just command line tools by doing the following:

@tmiw try dr-timing-bug branch. I can't seem to create a PR around this, GitHub is giving me web server errors on two machines. Good catch, and well presented - a recording and repeatable with the cmd line tools. Just the sort of repeatable bugs we want to track down from beta testers 👍

I noticed something strange in the Tx "over" of the sample around 59 seconds, it's seems to be pulsing the signal off and on at the end, around 59s. Have a listen to the sample and see what you think.

Strange pulsed audio from about 59 sec:

Might be an issue with how EOO is injected into the TX stream by freedv-gui. That will probably be something I'll need to look into once I'm ready to start on the reporting stuff.

Just tried this branch on freedv-gui and the above test file seems to decode without any problems now. 👍
