Typo in metadata_utils.generate_spherical_xml signature (equiretangular)

[5dqtstn-lab]

There is a spelling error in the default argument of the generate_spherical_xml function. The word "equirectangular" is missing the letter "c".

Here is the output from Python's inspect module:

from spatialmedia import metadata_utils
import inspect
print(inspect.signature(metadata_utils.generate_spherical_xml))
(projection='equiretangular', stereo=None, crop=None)
