1) Starting with this commit, configuration block exported into G-code
   is delimited by "; prusaslicer_config = begin" and "; prusaslicer_config = end".
   These delimiters look like any other key / value configuration pairs
   on purpose to be compatible with older PrusaSlicer config parsing from G-code.
2) Config parser from G-code newly searches for "; generated by ..."
   comment over the complete G-code, thus it is compatible with various
   post processing scripts extending the G-code at the start.
3) Config parser from G-code parses PrusaSlicer version from
   the "; generated by PrusaSlicer ...." header and if the G-code was
   generated by PrusaSlicer 2.4.0-alpha0 and newer, it expects that
   the G-code already contains the "; prusaslicer_config = begin / end"
   tags and it relies on these tags to extract configuration.
4) A new simple and robust parser was written for reading project configuration
   from 3MF / AMF, while a heuristic parser to read config from G-code located
   at the end of the G-code file was used before.
