Simplified the macro

Changed

• Overhauled several panic messages to make them less cluttered.
  • This also removes several steps of the condition analysis, so it might be less useful overall.
    Though arguably, assert conditions shouldn't reach that level of complexity to begin with...
• Allowed some conditions to only format their arguments on panic when it is known they won't be moved.
  • This will improve the performance in 95% of intended use cases, meaning this assert macro is now
    actually viable for production code rather than just test code.
