feat(rust)!: Import NamedFrom in df! macro

`Series::new` is not implemented on `Series`. This method is provided by
`NamedFrom` most of the time. This change makes `df!` explicitly use the
NamedFrom::new implementation, potentially causing a breaking change if
someone had defined another trait that provides a `new` method to
construct a `Series`.
