convert to package format

[spdegabrielle]

Sorry this is an incomplete transition.
If you install the package deepracket you should be able to (require deepracket)

If I got it right. Sadly I don't know enough about your Package to set up the tests etc.

I hope this is a step in the right direction.

Probably worth looking at https://blog.racket-lang.org/2017/10/tutorial-creating-a-package.html
