Remove coffee script for performance and tech debt reasons

[epugh]

Description

Converted our two .coffee scripts to .js

Motivation and Context

The "derailed" tool reported that coffee-script was .3 MB of memory, and while I thought we had tons of .coffee files, it turns out we only had two! Swapping from JS to coffeescript was always a werid cognitive swap as well.

Big thanks to the Decaffeinate project for the online REPL to convert the two files, it worked PERFECTLY. I might have left those two .coffee files thinking the conversion would be a real pain for a long time without the tool!
