> [R] Add chunk_size to Table$create()

> While working on ARROW-3308, I noticed that write_feather has a chunk_size
> argument, which by default will write batches of 64k rows into the file. In
> principle, a chunking strategy like this would prevent the need to bump up to
> large_utf8 when ingesting a large character vector because you'd end up with
> many chunks that each fit into a regular utf8 type. However, the way the
> function works, the data.frame is converted to a Table with all ChunkedArrays
> containing a single chunk first, which is where the large_utf8 type gets set.
> But if Table$create() could be instructed to make multiple chunks, this would
> be resolved.
