First release

This is the first official release of the Refrapy software, as published in the Computers & Geosciences paper.

Tested only on Windows 10 with Python 3.7.7.

Functionalities from Refrapick:

• Open waveform files (SEG2, SEGY and SU; uses obspy);
• See next/previous file;
• Increase/decrease time axis limit;
• Increase/decrease scale gain;
• Invert time axis orientation;
• Trim traces;
• View traces as wiggles or fill positive/negative side of amplitudes;
• Clip/unclip amplitudes;
• High pass/low pass filters and remove filters;
• Enable/disable pick mode;
• Connect/disconnect picks;
• Clear picks;
• Save pick file (.rp format)
• Enable/disable apparent velocity mode;
• View observed traveltimes with an interaction mode to highlight picks;
• Options (change a few parameters. e.g. gain factor)
• Change header info for plotting (e.g. receiver spacing, not actually changing the file header);
• Reset all.

Functionalities from Refrainv:

• Open pick file (.rp and .sgt formats);
• Next/previous panel (time-terms and tomography panels);
• Enable/disable layer assignment mode (for time-terms inversion, maximum of three layers);
• Clear layers assignments;
• Run a time-terms inversion (with/without elevation file);
• Edit traveltimes and save a new pick file;
• Create a pygimli's traveltime file (.sgt format);
• Run a traveltimes tomography inversion (with/without elevation file; uses pygimli);
• Reset;
• Edit velocity models plot (e.g. show/hide sources and receivers positions, change color maps etc.);
• Export velocity models;
