TPC: adding MC ccdb objects for simulation and reconstruction

[matthias-kleiner]

Digitization:

• adding loading of gas parameters from CCDB for tuning the electron attachment
• adding loading of GEM parameters for gain tuning

Reconstruction:

• adding option to load MC time gain calibration

Hello @wiechula ,
if this PR is fine, we need to upload the default CCDB objects for the MC time gain, the gas parameters and the GEM parameters. Do you want to open a ticket for this or should I do it?

which appears to be related to this PR (please make sure to upload CCDB objects (even trivial ones) for all runs). Uploading of those objects needs to be done prior to merging this PR.

[wiechula]

Yes, @matthias-kleiner will prepare an upload request with the default objects.

Here it is: https://its.cern.ch/jira/browse/O2-5562, already uploaded.

Hello @matthias-kleiner ,

This does not apply to async-v1-01-branch, if you wanted for PbPb 2023 apass4 MC, you should find the extra needed commits.
