Review Comment:
This is great! A couple of thoughts for how to expose this:
1. We can use this in `Table$create(schema = schema)`, i.e. where
`length(dots) == 0 && inherits(schema, "Schema")`. Currently we error if `...`
is empty.
2. This also can be the `as_arrow_table.Schema` method
3. Can also add `as.data.frame.Schema`, which is essentially what
`simulate_data_frame()` is now.
Doing these would solve the issue of exporting it for use in other packages.
