Release v2.3

• Replaced make_fcp_x3g Bash script with make_fcp_x3g.pl Perl script. This can be used in Windows without needing WSL. See the README for updated instructions. Those who are currently using the Bash script do not need to replace it, the functionality has not changed.
• Update config bundles for PrusaSlicer 2.3.
  • Add mediumStrong PETG profile (there is no mediumDetail PETG, it would be identical to the regular medium profile)
  • Use monotonic top & bottom infill except for rough profiles
  • Use gyroid infill in most profiles
  • Tweak number of top & bottom layers
  • Change resolution limit to just below the actual printer limit
