@eed3si9n just added the sbt.bat for windows changes

[ericdotdata]

@eed3si9n shit I missed something in the windows.bat converting to draft and I'll see about adding tests

[ericdotdata]

@eed3si9n back to active PR & CI passing, LMKWYT about the test refactoring

[eed3si9n]

@ericdotdata I'm 👍 on test refactoring.
