New processing steps in lstchain v0.7.0

Data sequence steps are now:

• r0 to dl1 step (same as before): dl1 and muons files as output (eventually we will keep only the muons files)
• dl1ab cleaning step using pedestal info: new dl1 files in a subdirectory running_analysis/dl1ab
• dl1 datacheck
• dl1 to dl2 (same as before): using dl1ab output files

New features:

• It improves the handling of options.test when -t option is enabled.
• It makes use of numba cache tmp directory.
• For the moment ctapipe-extra is needed to be installed.
• --nodl2 option
• sequencer table adapted to new steps
• keep symlink for muons files in running analysis
• properly move the dl1ab/datacheck files in closer
