Generalize to Callables Instead of Strictly Lambdas

[Jayson-Fong]

For fields that accept a lambda, generalize it to accept a callable in general.

This allows some code to be simplified for programs using the package. For example:

IntField(size=2, default=lambda s: len(s))

Can be simplified into:

IntField(size=2, default=len)

Also updated the CI to exclude Windows 2019 as it is no longer supported (see: actions/runner-images#12045)

Thanks Jayson. Change looks good.

Maybe it make sense to add at least one test that uses a callable...similar to lamba test

smbprotocol/tests/test_structure.py

Lines 369 to 379 in c3be43d

	def test_set_lambda(self):
	structure = self.StructureTest()
	field = structure["field"]
	field.name = "field"
	field.structure = self.StructureTest
	field.set_value(lambda s: 4567)
	expected = 4567
	actual = field.get_value()
	assert isinstance(field.value, types.LambdaType)
	assert actual == expected
	assert len(field) == 4

Also... maybe also enable Windows 2025 ?

The changes will need to be approved and merge by Jordan ... but I tool a look

Thanks again

Thanks for setting this up, I'm hoping to get to this by the end of the week.

The changes look good, just needs a rebase now that the CI has been updated.

[Jayson-Fong]

Applied the CI changes. Should be merge-able now.
