Argument overloading is not consistent for `supernova::supernova()`

[adamblake]

In the estimate extraction functions (b0(), b1(), fVal(), PRE()), you can supply either the result of lm() or the formula and data to be passed to lm(). This is not possible with supernova() which only accepts the result of lm().

library(supernova)

b0(lm(mpg ~ NULL, data = mtcars)) == b0(mpg ~ NULL, mtcars)
#> [1] TRUE

supernova(mpg ~ NULL, mtcars)
#> Error in supernova(mpg ~ NULL, mtcars) : unused argument (mtcars)

It would be nice to have supernova() overloaded to allow this and improve consistency.

Per our conversation, it might be better to not allow this. Specifying the model is an important part of understanding what is being tested.
