[Bug]: Compound dtype attributes are not supported

[rly]

What happened?

Compound dtype attributes are not supported, but the schema language says they should be: https://hdmf-schema-language.readthedocs.io/en/latest/description.html#attribute-specification-keys

Steps to Reproduce

NWBAttributeSpec(
                name="insertion_position_in_mm",
                doc=("Stereotactic coordinates (AP, ML, DV) of where the probe was inserted, in millimeters. "
                     "AP = anteroposterior coordinate in mm (+ is anterior). "
                     "ML = mediolateral coordinate in mm (+ is right). "
                     "DV = dorsoventral coordinate in mm (+ is up)."
                     "Coordinates are relative to `reference`"),
                dtype=[
                    NWBDtypeSpec(name="ap", dtype="float", doc="Anteroposterior coordinate in mm, relative to `reference` (+ is anterior).",),
                    NWBDtypeSpec(name="ml", dtype="float", doc="Mediolateral coordinate in mm, relative to `reference` (+ is right).",),
                    NWBDtypeSpec(name="dv", dtype="float", doc="Dorsoventral coordinate in mm, relative to `reference` (+ is up).",),
                ],
                required=False,
            ),

Traceback

TypeError: NWBAttributeSpec.__init__: incorrect type for 'dtype' (got 'list', expected 'str or RefSpec')

If this cannot be resolved soon, we should add it to the list at https://hdmf.readthedocs.io/en/stable/spec_language_support.html

I'll add this to my todo list. Thanks for the labels and milestone.
