Still problems with processing of single timsTOF files

[mschwoer]

Describe the bug
The error described in #434 still occurs on machines with > 60 cores, regardless of the n_processes settings.

[mschwoer]

The root cause is that the n_processes settings are not propagated to score.py:train_RF(). Thus, the default value n_jobs: int = -1 is always used there, which makes GridSearchCV (according to doc) always use the maximum number of cores available. If this is bigger than 60, the crash described in #434 occurs.

Suggested solution:

• pass n_processes settings to score.py:train_RF().
• (optional) to make train_RF() itself robust against this issue, introduce another cpu core check (similar to the solution in 7e989bc)
