Error with "-p warning" argument in the "gemos analyze dac" command

Description

Trying to run the dac scan analysis (gemos analyze dac) with the optional argument -p warning causes an error such as the following:

  File "/afs/cern.ch/user/d/destrada/private/cmsgemos-analysis/gemos/analysis/dac_scan_analysis.py", line 229, in create_configuration
    plot_scan(input_df, output_df, output_dir / "plots")
  File "/afs/cern.ch/user/d/destrada/private/cmsgemos-analysis/gemos/analysis/dac_scan_analysis.py", line 168, in plot_scan
    dac_scan_axs[group_index].plot(
.
.
.
ValueError: setting an array element with a sequence

Steps to reproduce

Taking as input files those available in /afs/cern.ch/work/c/cgalloni/public/4Yechan/ the command would be:

gemos analyze dac 4Yechan/dacScan/*.txt test_out/ -m 4Yechan/vfat_map.dat -c 4Yechan/vfat_calibration.txt -p warning

Possible fixes

When -p warning argument is passed, the data are filtered before to perform the plots (dac_scan_analysis.py-line 211). So, the problem may be here.

The error appears in dac_scan_analysis.py-line 168, because chousen_dac is not a single value but a list, that does not happen when the data are not filtered.
