Repo reorg: edge smoothing, interpolation, and pixel art scaling (#469)
* Move initial batch of shaders and presets to smoothing subdirectory

* Rename smoothing to edge enhancement

* Move cubic and windowed into interpolation

* Fix some presets

* Fix rest of presets

* Rename edge-enhancement to edge-smoothing

* Move pixel art scalers into separate directory separate from 'interpolation'

* Flatten interpolation/cubic into interpolation/
