User requested changes to tsv files

[jehibbard]

During a recent CARTA webinar we gave at NRAO, a user (Peter Teuben from Maryland) asked whether CARTA output text files that could be used by other software (to plot or do statics). I sent him a .tsv file from a histogram and from spectral fitting. He had the following comments:

• the default name for the tsv file was named something like "-Z-profile-Region_1-Statistic_FluxDensity-Cooridnate_Current-2022-08-25-16-50-14.tsv, which has a typo (Cooridnate instead of Coordinate)

• don't allow spaces in filenames (the files I sent him did not have spaces in their names, so maybe this is already done)

• Make sure there is not a blank line at the end, which he has seen programs/compilers fail on
