Description
With numpy 1.22, astropy fails to aggregate table columns of non-native endianness. This works with numpy 1.21.
Expected behavior
With numpy 1.21.5:
>>> import numpy as np
>>> from astropy.table import Table
>>> table = Table({'foo': np.arange(10, dtype='>f8')})
>>> table['bar'] = table['foo'] % 2
>>> table.group_by('bar').groups.aggregate(np.sum)
<Table length=2>
foo bar
float64 float64
------- -------
20.0 0.0
25.0 1.0Actual behavior
With numpy 1.22.0:
>>> import numpy as np
>>> from astropy.table import Table
>>> table = Table({'foo': np.arange(10, dtype='>f8')})
>>> table['bar'] = table['foo'] % 2
>>> table.group_by('bar').groups.aggregate(np.sum)
WARNING: Cannot aggregate column 'foo' with type '>f8' [astropy.table.groups]
<Table length=2>
