=str - Various Flow and FlowMaterializer improvements

Browse source 
- Switches from using size-of-1/2 Vectors to using Lists
  - Fixes an issue where processorForNode wouldn't use the dispatcher form the settings
  - Adds a dedicated Collect fusion op
  - Adds various simplifications to ActorBasedFlowMaterializer
  - Adds FIXMEs where appropriate
  - Switches `grouped` to use a VectorBuilder
  - Adds support for `scan`
  - ActorBasedFlowMaterializer now uses Iterator instead of head+tail decomp on Seqs
  - Identity and Completed Transformers are now cached
  - Adds dedicated AstNodes for all combinators
  - Adds a hook-in point for fusion in `ActorBasedFlowMaterializer`
  - Adds support for `Operate` an AstNode with a function that create a fusing.Op
  - Adds experimental and slow optimizer as a PoC
  - Adds verification that Ast.Fused does not exist in optimizer input
