Adding an option to append a content hash to the end of font files for cache-busting on glyph changes

[john-positano]

@patrickhulce Did you mean "check that on my end" or did you want a test module written to go along with these changes?

a test module written to go along with these changes

[john-positano]

@patrickhulce I wrote a test to make sure that the hashes appended to the font filenames are referenced in the final assets, that's pushed

thanks very much @john-positano!

a quick patch to fix the lint failures and we're on our way 🎉
