Allow for more than 3 dimensions in the bbox #144

The GeoJSON spec recommends 2 or 3 dimensions, but does not forbid geometries that have more. See https://www.rfc-editor.org/rfc/rfc7946#section-3.1.1.

In addition, the bbox length is 2*n where n is the number of dimensions. See https://www.rfc-editor.org/rfc/rfc7946#section-5.

See my comment at https://github.com/opengeospatial/geoparquet/pull/88#issuecomment-1320479016, we currently only allow 2D or 3D.
