Deprecate duplicate functions, update existing ones

[LightArrowsEXE]

This PR does the following:

• Deprecates functions that have (basically) equivalent functionality with existing functions in the interest of reducing code duplication and people trying to run the exact same functions from multiple *funcs
• Update existing functions with updated tooling that should both run faster and be more resistant to unintended user input
• Improve some typing and make a the package overall a bit more Pythonic, as we ll as make it a tad more typesafe in certain scenarios
• More useful and informative exceptions
• Expand some functions with functionality that can be built on in the future (i.e. presets)

The biggest "drawback" for the common users of this *func is more reliance on iew-related packages. That said, most of the direct iew usage should be mitigated and abstracted away, so it should not require users learn how to use those functions per se (though of course, in my personal opinion, they should lol). The deprecated functions currently work as wrappers around those instead.

Fixed a couple of things.

@Setsugennoao @LightArrowsEXE It looks like vsdenoise.fft3d isn't in the latest published pip version, could I trouble whoever has the ownership to push a new release?

[Setsugennoao]

Sure, i'll do it tomorrow.

I have no idea why git closed this when I pushed up changes. :facepalm:

[shssoichiro]

Oh because git is terrible (for usability) and it pushed my main to light's main because he didn't name his PR branch something other than main. :facepalm:

[shssoichiro]

Now git is saying I don't have permissions to push to light/main, even though I just did it before. I guess I just have to recreate the PR. :facepalm: :facepalm: :facepalm: :facepalm:

[Setsugennoao]

Lol, has happened to me a couple of times. Pushed the changes again btw.
