Possibility to inactivate fractions missing

[sebastian-vw]

Describe the bug
In the new AlphaPept version 0.3.31 support of fractions is implemented. When a new experiment is created, all runs are automatically assigned fractions 1 to x. I am not sure what to do when no fractions should be used. I tried to put the fraction from each file to 1, but this doesn't work if many files (>100 are loaded), because there is no function to change the fractions for all files at once and changing file by file takes very long.

To Reproduce
Create a new experiment with version 0.3.31 and observe the file overview. Fractions are automatically assigned to each file. I couldn't find a button to inactivate fractions or change all fractions to the same number (to mimic no fractions).

Expected behavior
Time-consuming manual changing of the fraction for each file is necessary and thus this is only possible up to a limited number of raw files to be analyzed.

Version (please complete the following information):

• OS: Win10 Pro
• Version 0.3.31
• Installation Type: Python

Additional context
It would be great to include a button to inactivate the fractions or at least introduce the option to change the fraction label for all files at once (e.g. to 1).

The idea behind this fraction implementation is that all files that share the same fraction will be scored together. Currently, when loading them they'll be enumerated and each has a unique number, so no file will be in the same fraction, effectively treating them as if there were no fractions.
I could add a note here that explains this behavior.

Thanks for the explanation!
