Documentation request: add these projection details to Intro/Vignette PDF about usmap HOT 4 CLOSED

@ricobert1 That's a good idea, I'll add it in for the next update.

from usmap.

@ricobert1 do you think there would be any value in also providing a function that allows the user to easily transform any shapefile using that transform?

I'm thinking of something like this:

shapefile <- readOGR("...")
transformed_shapefile <- usmap_transform(shapefile)

Where the usmap_transform function (open to name suggestions) would apply the transform that was used on the original map and maybe account for possible differences in shapefiles that are used as input.

@ricobert1 I've added a new vignette called "Advanced Mapping" which includes the projection details. There's also a new function usmap_crs() which provides the projection as a coordinate reference system (CRS) object used by the sp package. It will be in the next CRAN release, thanks for your suggestion.

@ricobert1 usmap 0.5.0 is now publicly available on CRAN which includes the aforementioned changes, thanks for your input!
