Bug: pplt.rc.load does not work properly

Description

pplt.rc.load does not work properly. I found the problem when I was playing with ~/.proplotrc. The same problem appears as in the following example.

Steps to reproduce

I save a rc file as follows

import proplot as pplt

pplt.rc['font.size'] = 10
pplt.rc['axes.labelsize'] = 'med-large'
pplt.rc.save('proplotrc', comment=True, backup=False, description=True)
pplt.rc['font.size'],pplt.rc['axes.labelsize'], pplt.rc['label.size']

It prints (10.0, 'med-large', 'med-large')

The file is indeed updated with the lines

# Changed settings
label.size:     med-large
axes.labelsize: med-large
font.size:      10.0

Then I restart the session and load the same file as follows

import proplot as pplt
pplt.rc.load('proplotrc')
pplt.rc['font.size'],pplt.rc['axes.labelsize'], pplt.rc['label.size']

It prints (10.000000000000002, 'medium', 'medium').

Proplot version

Paste the results of import matplotlib; print(matplotlib.__version__); import proplot; print(proplot.version)here. 3.4.3 0.9.5.post259

This is fixed by 6ea48d5. The issue was that in the proplotrc file, font.size came after label.size. The internal implementation of _load_file caused the font.size setting to overwrite your label.size with the default value.

Now your example

import proplot as pplt
pplt.rc.load('proplotrc')
pplt.rc['font.size'],pplt.rc['axes.labelsize'], pplt.rc['label.size']

correctly prints (10.000000000000002, 'med-large', 'med-large').

Many thanks for the quick fix!!!
