v1.14.0-alpha COMET LiCSBAS

This is the first release of the COMET team outside of the original LiCSBAS by Dr. Yu Morishita: https://github.com/yumorishita/LiCSBAS

COMET LiCSAR team of developers performed various improvements over the original code base.
Main updates are:

• step 11 - extra check for readability and dimensions of input unwrapped interferograms
• step 11 - extra check for ionospheric ramps
• step 12 - nullification of pixels with loop closure errors, rather than dropping whole interferograms from the inversion
• step 13 - added options 'only_sb' and 'singular' for faster solution (less computational demands, but 'singular' might be less precise than NSBAS)
• step 14 - added option 'ransac' to additionally bootstrap-estimate velocity, avoiding outliers in cummulative increments. to be parallelised in the next release
• LiCSBAS_out2nc.py - improved export to standard (GIS-compatible) NetCDF (to be further improved)

We intend to (soon) merge the updates with the current revision of the original LiCSBAS in the next release - and then focus on v2.0 - stay in touch!
