Investigate ConMon plot_time_ps.sh and plot_time.sh warnings

[EdwardSafford-NOAA]

Under low-data conditions (4-8 cycles of extracted data) the plotstas_time_count_ps.gs script produces gaaxis internal logic check 24 warnings. This condition does not seem to occur if more data is available. The plotstas_time_count.gs script produces similar errors with data types uv220 and uv282.

Additionally plotstas_time_bias.gs and plotstas_time_bias2.gs scripts produce 'gaaxis internal logic check 25' warnings for data types uv282, uv284, uv291, and uv296. In these cases one of the four plots in a given image is missing the y axis scale, though the line plot is produced.

Since this isn't an error, and occurs in atypical conditions, this is considered a low priority issue.
