facet_grid() fails if passed both a formula and a vars()

`rows` must be `NULL` or a `vars()` list if `cols` is a `vars()` list.

can't pass formulas to cols

`cols` must be a `vars()` specification or `NULL`, not a <formula> object.

facet gives clear error if

A grid facet specification can't have more than two dimensions.
`cols` must be a `vars()` specification or `NULL`, not the string "free".

at least one layer must contain all facet variables in combine_vars()

At least one layer must contain all faceting variables: `letter`
x Plot is missing `letter`
Layer is missing `letter`

combine_vars() generates the correct combinations

At least one layer must contain all faceting variables: `b` and `c`
x Plot is missing `c`
x Layer 1 is missing `b`
Faceting variables must have at least one value.

validate_facets() provide meaningful errors

Please use `vars()` to supply facet variables.
Please use `vars()` to supply facet variables.
i Did you use `%>%` or `|>` instead of `+`?
