Describe the Problem

While answering a met-help question for RT 9891 from the UK MetOffice, I tested out the set_attr options to manually define the gridded metadata. During that testing, I found that set_attr_accum does not have the desired effect. It sets the lead time instead of the accumulation interval.

It's a simple copy/paste error that's a one-liner to fix.

Expected Behavior

Defining set_attr_accum should actually override the accumulation interval read from the input data file.

Environment

Describe your runtime environment:
1. Machine: Replicated behavior on my Mac
2. OS: MacOS
3. Software version number(s): exists in met-9.1.2 and in the develop branch

To Reproduce

Describe the steps to reproduce the behavior:
1. Go to the top-level MET directory of the develop branch and run:

bin/plot_data_plane \
data/sample_fcst/2005080700/wrfprs_ruc13_12.tm00_G212 plot.ps \
'name="TMP"; level="Z2"; set_attr_accum="37";'
-v 4

2: Note these 2 log message:

DEBUG 3: Parsed set_attr_accum = "37"
DEBUG 4:      accum time: 000000

So it parsed it correctly but did not apply it correctly.
