also send interpretation into array interfaces

thanks BSAIPF

see #1429

LGTM! I think this only affects cases where obj.__array__() is backed by an __array_interface__ attribute, since interpretation isn't used otherwise.

Oh hmm, perhaps the:

        if isinstance(obj, list):

case could pass interpretation along as well?

[jcupitt]

I had a quick look and adding interpretation to new_from_list is not a trivial change. Let's leave it for another PR.

Indeed, interpretation is only used by:

pyvips/pyvips/vimage.py

Lines 539 to 543 in b243fff

	if interpretation is not None:
	if interpretation == 'auto':
	interpretation = _guess_interpretation(bands, format)
	im = im.copy(interpretation=interpretation)

as documented here:

pyvips/pyvips/vimage.py

Lines 463 to 475 in b243fff

	interpretation (str, optional): **Ignored for list inputs** The
	libvips interpretation of the array. If None, the
	interpretation defaults to the pyvips one for
	`Image.new_from_memory`.
	If 'auto', a heuristic is used to determine a best-guess
	interpretation as defined in the `_guess_interpretation`
	function.
	Must be one of None, 'auto', 'error', 'multiband', 'b-w',
	'histogram', 'xyz', 'lab', 'cmyk', 'labq', 'rgb', 'cmc', 'lch',
	'labs', 'srgb', 'yxy', 'fourier', 'rgb16', 'grey16', 'matrix',
	'scrgb', or 'hsv'
