Hi, this code is improvement of previous pull request #256 which adds shower name to full video by parameter : "-w", "--add_shower_name" (even without meteor image at the end)
It fixes shower name identification in case if image contains more than 1 meteor
This is a fix for cases when we have several tracked meteors on on same fits file and identification was wrong as it took first meteor from list
Implemented solution: Usage of meteor start and end time to compare with start and time of bin video (calculated by frame number) If meteor time range inside video time range - this is the best candidate.
Also during testing found that video could start with small lag (1 or 2 frames later) . To fix it was introduced time offset for 100mls before and after video start (if fps is 25 then 1 frame ~40mls ) It fixed issue on my test suite.
What was not tested: As I can see bin file could be multi lines and I don't have such example and don't know when such file could be created, also exists option '--split' which also could affect calculation.
This solution will not work for simultaneous two or more meteors at same time but I think it is very rare case and need identification meteor by coordinates on video (very complex for me).
