allow use of sk_sg_filter by passing channel bandwidth and sampling interval

[mef51]

sk_sg_filter only uses foff and tsamp from the Your class and I wanted to apply this on waterfalls without having to instantiate this class to use it. This change allows either use case: use with your_object or optionally pass foff and tsamp instead

@mef51 thanks for the PR, this looks like a good idea! Can you please run black on the your code?

[mef51]

@devanshkv sure, done

@mef51 can you please modify the following test to include cases for your code:

your/tests/test_rfi.py

Lines 46 to 56 in 3d286d9

	def test_incorrect_sigmas(fil_file):
	your_object = Your(fil_file)
	data = your_object.get_data(0, 1024)
	with pytest.raises(ValueError):
	sk_sg_filter(data, your_object, -1, 1, 1)
	with pytest.raises(ValueError):
	sk_sg_filter(data, your_object, 3, 15, -1)
	with pytest.raises(ValueError):
	sk_sg_filter(data, your_object, 0, 15, 0)

The test was failing because of the different signature. I moved the new kwargs to the end of the arg list to preserve the signature. Also added a test case for the new kwargs

Awesome! Thank you so much! We are going to make a release soon and will make sure to detail your contributions and tag you.
