Catch runtime errors when smoothing spectra

[krisvanneste]

Small fix to avoid program ending when a runtime error occurs during smoothing of a spectrum.
I ran into this problem when running sourcespec on > 200 earthquakes.
It should be easy to propagate this fix to v2 as well.

Hi Kris, thanks for this PR.

One of my future goals is to replace all generic except Exception with specific exception handling. Do you know which kind of exception is raised in this case?

If it is a RuntimeError, I would prefer to handle it as except RuntimeError.

Thanks 😉

Claudio,
It was one of the ValueErrors that can be raised in the smooth() function in ssp_util.py, more specifically:

ValueError('Input vector needs to be bigger than window size.')

If you want, I can try running it again on one of the problematic cases to see if it gets caught with except ValueError.

[claudiodsf]

Yes, please. In principle, that should work with except ValueError.

The idea behind handling specific errors is to more easily discover unexpected ones when they occur 😉

[krisvanneste]

OK, I will test.

[krisvanneste]

It works, the exception gets caught. Shall I commit or are you going to replace generic exceptions in a separate branch?

[claudiodsf]

Please commit!

[krisvanneste]

Done!

Merged! Also, rebased v2 on this commit 😉
