readgssi: an open-source tool to read and plot GSSI ground-penetrating radar data

This version of readgssi (called Bromley) adds several major features and bug fixes. The most significant of these are support for the StructureScan Mini XT, improved handling of multiple antenna frequencies, improved faint layer plotting (tested on cold-based blue ice data), improved handling of GSSI's pauses (which misalign GPS epochs and radar trace numbers after a user-initiated pause), and the ability to add vertical user marks to plot output.

Version 0.0.17 "Bromley" continues the naming scheme based on names of mountain peaks in the Williamstown, Massachusetts area.

changes since 0.0.16

• merged #19 from teshaw which allows the user to specify partial read parameters for DZT files
• reintroduced a testing feature which creates CSV files from DZG records, in order to easily import location information to GIS
• added support for the StructureScan Mini XT which suffered from the unfortunate fate of having an antenna named 'none'
• improved handling of multiple user-specified frequencies
• adding the ability to plot the absolute value of the down-trace gradient, which can increase faint layer visibility at the cost of wave front resolution
• now use rf_top to correct depths, a major bug in previous versions
• limited distance normalization console output to one message every ten chunks (in the future, this will be controlled with a \r statement)
• added pause correction function to fix DZG/DZT trace number offset when collection is paused and GPS is active
• added ability to plot user marks as vertical lines (similar to the output on the controller itself)
• corrected module call documentation for plotting (#23)
