+ solid_earth_tides.py:
   - add --comp enu2los / en2az to switch between range / azimuth direction output
   - use ut.get_unit_vector4comp_of_interest() for --comp projection
   - support date_list text file as input, as an alternative to the TS HDF5 file
   - change set_file as optional arg in calc_solid_earth_tides_timeseries()

+ bulk_plate_motion.py:
   - add --comp enu2los / en2az to switch between range / azimuth direction output
   - use ut.get_unit_vector4comp_of_interest() for --comp projection
   - use lower case "enu" and/or "az" for default output filename
   - set pmm_file as optional arg in calc_bulk_plate_motion()

+ utils.utils0.py:
   - add Coordinate / Orbit sub-section to simplify the Geometry sub-section
   - add definition with example values for the following angles: los_inc_angle, los_az_angle, orb_az_angle, head_angle
   - add los2orbit_azimuth_angle()
   - add azimuth2heading_angle(look_direction) and heading2azimuth_angle(look_direction)
   - add en2az()
   - add get_unit_vector4comp_of_interest()
   - add misregistration2coherence() based on Just & Bamler (1994)

+ utils.utils.prepare_geo_los_geometry(): change the output from head_angle to los_az_angle.

+ smallbaselineApp.plot_result: rm '-u cm' for velocity, as it now has datasets with different units, thus, '-u cm' won't work anymore.

+ del simulation/configSenDesc.txt, as it's not used in the code anymore.

+ objects.timeseries.read(): use single indexing to speedup IO

+ objects.ionex: move plotting-related modules inside plot_ionex() for more independency

+ view: update example usage in the comments for (cli)/view.py

+ tsview: fix the mpl.figure.canvas.set_window_title() bug, as reported and fixed by Jiawei Li

+ use MACRO_CASE for the global variables defined in objects/stack.py and objects/giant.py. Update their usages throughout mintpy repo.

+ other minor codacy suggestions
