Make file reading more robust

[charlieforward9]

Fit files seem to have an issue every now and then... I am using the dependent library https://github.com/dodo-saba/fit2gpx

Traceback (most recent call last):
  File "/Users/crich/development/github/NEW_HEAT/strava_parser.py", line 127, in <module>
    strava_conv.strava_fit_to_gpx()

    raise FitHeaderError(f'not a FIT file @ {self._chunk_offset}')
fitdecode.exceptions.FitHeaderError: not a FIT file @ 0

I tried putting the fit file into FitFileViewer as well, and got an error. However, when I try to convert the fit file to gpx with GoToes, it works without any problem.

It would be nice to have a handler that reads the fit file using the same type of error handling as gotoes, such that it does not crash the parsing.
