Add “tables” to the tests-deser extra

[musicinmybrain]

Enables one additional test.

param/tests/testfiledeserialization.py

Lines 63 to 66 in b6a285b

	try:
	import tables as hdf5
	except:
	hdf5 = None

param/tests/testfiledeserialization.py

Line 76 in b6a285b

hdf5_skip = skipIf(hdf5 is None, "pytables is not available")

param/tests/testfiledeserialization.py

Lines 205 to 213 in b6a285b

	path = '{}/val.h5'.format(self.temp_dir)
	P.data_frame.to_hdf(path, 'df')

tables is actually installed when the CI runs on Linux:

param/pyproject.toml

Lines 191 to 196 in e9b2781

	# Only install gmpy on Linux on these version
	# Only install tables (deser HDF5) on Linux on these version
	matrix.python.dependencies = [
	{ value = "gmpy", if = ["3.8", "3.9", "3.10"], platform = ["linux"] },
	{ value = "tables", if = ["3.8", "3.9", "3.10", "3.11", "3.12"], platform = ["linux"] },
	]

And you can verify the test is not skipped:

It's just that the dependencies declaration is a little convoluted in pyproject.yml, and that in the end the tests-deser isn't used at all. I'll merge your PR though since anyway tables should be in tests-deser.
