Design data encoder solution

[andrewmusselman]

• research if/how these are implemented in each backend
• research the different methodologies to assess scope
  • enumerate strategies e.g. Basis, Amplitude, etc
  • document constraints e.g. whole-dataset vs individual
  • compatibility with various kernel methodologies
• research what data structures are needed to keep computation backend-agnostic
• decide what needs to be built in qumat
  • integrate backend implementations
  • build utilities from scratch
