Need to investigate and possibly fix warnings generated during tests

[samaloney]

Describe the bug

I had to add the following to the pytest config to get the tests to pass:

sunkit-spex/setup.cfg

Lines 64 to 80 in 2257afb

	filterwarnings =
	error
	# https://github.com/pytest-dev/pytest-cov/issues/557
	# It was fixed and released but it does not seem to be fixed
	ignore:The --rsyncdir command line argument and rsyncdirs config variable are deprecated.:DeprecationWarning
	# Raised by sunpy.coordinates.transformations and will be removed in sunpy 6.1
	ignore:.*module is deprecated, as it was designed for internal use
	# https://github.com/pandas-dev/pandas/issues/54466
	# Should stop when pandas 3.0.0 is released
	ignore:(?s).*Pyarrow will become a required dependency of pandas:DeprecationWarning
	# TODO review and fix just getting test running
	ignore:numpy.ndarray size changed.*:RuntimeWarning
	ignore:Some input energy values outside valid range.*:UserWarning
	ignore:invalid value encountered in.*:RuntimeWarning
	ignore:divide by zero encountered in.*:RuntimeWarning
	ignore:The truth value of an empty array is ambiguous..*:DeprecationWarning
	ignore:LinAlgError when calculating the hessian. Errors may not be calculated.:UserWarning

Need to remove these one by one and check if can really "safely ignore" or need to update the code.
