Introduce Live FIFO-Sizing

[fpjentzsch]

Iterative live FIFO-sizing
Supports bitstream & driver generation for ZYNQ platforms.

Usage instructions for builder config:

• cfg.live_fifo_sizing = True
• cfg.enable_instrumentation = True
• cfg.generate_outputs = ["bitfile", "pynq_driver", "deployment_package"]

Usage instructions for driver:

• Run driver.py from deployment package
• Supply at least the --settingsfile argument, pointing to the generated settings.json
• Driver will generate
  • fifo_sizing_report.json
  • fifo_depth_export.json
  • folding_config_lfs.json (combined folding config + FIFO depth export)
  • fifo_sizing_graph.png (plot showing search phase 1)
  • measured_performance.json (final performance report from instrumentation)

Depends on / includes:

• Integrate Instrumentation into Zynq Backend #45
