ignore python3 cache, generated code files

add option to export Profile (and thus stream too) to Python code
add for each profile in functional tests generating it to Python code and comparing to same pcap result
add loading Prifile via add_streams()
fix IMIX rates in HLTAPI used with line % and bps
Scapy packet builder: fixes to load of pcap/yaml - use MAC from pcap (with flag), remove FCS (with flag), support for VM with offsets by name
