Gdsfactory

- simplify technology into a separate module [PR](https://github.com/gdsfactory/gdsfactory/pull/1014) [PR](https://github.com/gdsfactory/gdsfactory/pull/1102) [PR](https://github.com/gdsfactory/gdsfactory/pull/1109). You need to rename:
- LAYER_COLORS -> LAYER_VIEWS
- layer_colors -> layer_views
- gf.layers.load_lyp -> gf.technology.LayerViews.from_lyp
- GENERIC -> GENERIC_PDK
- gdsfactory.tech -> gdsfactory.technology
- gdsfactory.geometry.get_xsection_script import get_xsection_script -> gdsfactory.generic_tech.get_klayout_pyxs import get_klayout_pyxs
- get_xsection_script -> get_klayout_pyxs
- move klayout to gdsfactory/generic_tech/klayout, you will need to run `gf tool install` to link `klive`

- add Implant simulation [PR](https://github.com/gdsfactory/gdsfactory/pull/1106)
