FST: Extend FST to allow for ITS-GPU reco

[mconcas]

Before merging:

• Fix funny behaviour not finding clusters in FST scripts but works in manual gpu-reco-workflow invocation
• Uncompress the clusters
• Write ITS tracks

Requires: AliceO2Group/O2DPG#1951

why do you do this only for CTFINPUT=1, I think this should be global?
Simiar for the GPU_OUTPUT above. In principle, I'd set the ITS input and outputs in GPU_INPUT and GPU_OUTPUT at the same place to avoid confusion.

Otherwise looks good now 👍
Let me know when it is working :).

Ok, I connected also the writer, now it should be functional. Tested in PbPb with:

#! /bin/bash -x

rm -f /dev/shm/*fmq*;

export WORKFLOW_DETECTORS=TPC,ITS
