Create interfaces between reconstruction methods and libertem about ptychography HOT 3 CLOSED

Minimal example:

• Stand-alone Python script
• Minimal Alpaka routine ("hello world" style, for example a sum to check correctness)

• Two Python functions:
  • init() to set up data structures
  • Repeated calls to process() that moves data into the structures, triggers the Alpaka processing and receives the result
