Update package to use workflows, lint package

[elimillera]

@pburnsdata, Did the first pass of the package. I added coverange, linting, and an R CMD check. The lintr was getting mad at the commented code so I deleted it. If it looks like we need to keep that we can add that in.

Wow fantastic work @elimillera , we've got the snazzy check and you got all us all the way to CRAN ready O: Thanks for cleaning up code comments, I think only one that might come back is the code for making normalization general - I'll make issue for that one. I suspect we can cut down the vars we're sticking in zzz.r to clear the check, but this is perfect for now
