Description of the desired feature

Just want to share a few ideas. Please feel free to move this elsewhere.

• start all scripts with mp_*. This allows to see the script names by typing mp_ TAB

mp_t
mp_timeseries_rms.py         mp_tropo_gacos.py            mp_tropo_phase_elevation.py

(it would make it easy to combine MIntPy with Non-Mintpy scripts)

• write all executed commands in a .commands.log file. This would make it easy to rerun a command from the workflow using different options. And it keeps a log of manually executed commands.

• support --subset-lalo 19.43:19.51,-155.65:-155.54 format (currently only used in *template control files). This is described in detail in Enhancement suggestion: --subset-lalo LATMIN:LATMAX,LONMIN LONMAX option for view.py #1045.
