Sorry, something went wrong.
We can now regenerate a TPC digit file using the TPC chunked-digit merger.
This is useful when we have the TPC "drift-time" digits (as in O2DPG) and want
to obtain the full timeframe of TPC digits in ROOT file tpcdigits.root.
There is a new special mode for this and the command line to use is
```
${O2_ROOT}/bin/o2-tpc-chunkeddigit-merger --writer-mode --tpc-lanes 8
```
for the case in which we had 8 separate lanes of drift-time digits.
This commit includes:
* small modularity and library refactoring
* do not fatal in the TPCDigitRootWriter if no triggers are sent
* merging/treatment of the TPC common modes in the merger (so far not done)
