Simplify pipeline creation, vectorize FFTHEADmaster

- Add a script to create a pipeline & assets in a single click
- Add pipeline executor concept. This exists to (theoretically) let
  users merge the results of multiple pipelines.

-    Udon# Linear Pipeline Controller
-
-    This script manages a linear chain of image effects. It takes a source texture
-    and processes it through a sequence of materials, storing the result of each
-    step in a corresponding RenderTexture.
-
-    Setup:
-    1.  Create an empty GameObject in your scene.
-    2.  Add an UdonBehaviour component to it.
-    3.  Create this Udon# script in your project and assign it to the UdonBehaviour.
-    4.  Create all the Materials and RenderTextures you need for your pipeline.
-    5.  In the Inspector, assign the Source Input, Materials, and Output RenderTextures.
-        - The size of the Effect Materials and Pipeline Outputs arrays MUST be the same.
-        - The order of materials and textures in the arrays determines the pipeline order.
-    6.  Choose your desired execution mode (Run On Start, Run Continuously).
