astropy: Table cannot read numpy void dtype

Description

Cannot read a Table from a file with a numpy.void dtype column.

Expected behavior

Roundtripping for all numpy array types.

Actual behavior

A ValueError is raised that void is not a recognized dtype

Steps to Reproduce

import tempfile
import os

with tempfile.TemporaryDirectory() as tempdir:

    tbl = QTable({"a": [u.Quantity((0, 0, 0.6), unit="(eV, eV, eV)")]})
    tbl.write(os.path.join(tempdir, "temp.ecsv"))

    QTable.read(os.path.join(tempdir, "temp.ecsv"))

ValueError: datatype 'void192' of column 'a' is not in allowed values ('bool', 'int8', 'int16', 'int32', 'int64', 'uint8', 'uint16', 'uint32', 'uint64', 'float16', 'float32', 'float64', 'float128', 'string')
