Support ND2 files

[normanrz]

ND2 is a format from Nikon and is supported through the nd2reader package. ND2 is often used for fluorescence light microscopy (maybe multiple layers).

Sample code:

from nd2reader import ND2Reader

a = ND2Reader(input_path)
size = a.metadata['pixel_microns'] * 1000
a = np.stack(a).T
print(a.shape, a.dtype)

This is already supported via the pims bioformats reader in Dataset.from_images(), see also #826 and #825. Closing therefore.
