Parsing of scan number

[michabirklbauer]

This really should use a proper function to parse scan numbers, as this might not always work:

MSAnnika_Spectral_Library_exporter/create_spectral_library.py

Line 59 in e952168

scan_nr = int(spectrum["params"]["title"].split("scan=")[1].strip("\""))

For the moment, make sure that the title contains scan= with the scan number, otherwise script won't work.

For future, use something like here: https://github.com/hgb-bin-proteomics/Proteome_Discoverer_MGF_Scan_Number_Repair_Tool/blob/f59c4a667641e75c3ae42fa53496aae7938ba0a3/scan_nr_repair_tool.py#L75
