Masked ``_array2string`` doesn't work on some structured arrays

See original GitHub issue

Description

The dispatch function _array2string in masked.function_helpers doesn’t work on arrays with strutcured dtypes.

Expected behavior

Masked arrays with structured dtypes can be printed no prob, like their non-masked counterparts.

Actual behavior

It errors because of the structured dtype.

Steps to Reproduce

Here’s an example:

from astropy.utils.masked import Masked
from astropy.uncertainty import Distribution

arr = np.array(Distribution(((np.random.beta(2,5, 10000)-(2/7))/2 + 3)))  # just for convenience.
x = Masked(arr, mask=False)

repr(x)

While the following works:

repr(arr)
