hls4ml report command

Created by: vloncar

This adds hls4ml report ... as an additional command to hls4ml that prints the Csim and synthesis reports. It replaces the previous script used in the tutorial.

Usage: hls4ml report -p my-hls-test -f where -p points to the generated hls4ml project (NOT Vivado project like myproject_prj) and -f or --full optionally shows the full report (otherwise only the basic latency and resource utilization will be reported).
