Add precip bucket accumulation plots

Describe the New Feature

UPP outputs total (runtime) accumulations, no buckets (e.g. 1-hour or 6-hour accumulations). Add code to derive these fields. To avoid too many issues with data availability, could start by automatically plotting bucket accumulation based on output frequency only. E.g. use runtime fields to compute hourly buckets if output freq is 3600sec. Create plot on GUI for these derived fields as well.

Acceptance Testing

UPP grib2 output files will be used to compute these derived fields, along with output_frequency from user interface parameters. New derived fields should contain bucket accumulations according to output frequency.

Time Estimate

3-5 days

Start by locating the UPP GRIB2 output handling, the output_frequency user-interface parameters, and the GUI plotting code. Determine how runtime precipitation fields are represented, then implement derived bucket accumulations and expose them to the plot view. Done means UPP GRIB2 files and the configured output frequency produce bucket fields that can be plotted.
