simpler generic PDK customized components

[joamatab]

How about using UnPack instead of partial for customizing PDKs?

https://typing.readthedocs.io/en/latest/spec/callables.html#unpack-kwargs

import gdsfactory as gf
from typing import Unpack


@gf.cell(post_process=[gf.add_padding, gf.add_pins.add_pins])
def straight_sc(**kwargs: Unpack[gf.c.Straight]):
    return gf.components.straight(**kwargs)


if __name__ == "__main__":
    c = straight_sc()
    c.show()

Seems like a nice way to type components based on other components.

I wonder would it be easy to generate the TypedDict from a component function automatically, just by looking at which keyword arguments have defaults available and applying NotRequired to those.

One caveat through: Unpack seems to only be available in python 3.12+ for kwargs PEP692

It worked for me on 3.11

I think this is a better solution
