Misc:

• Various refactoring, cleanup, and improvements

Changes:

• Renamed stacktrace_frame.address -> stacktrace_frame.raw_address
• Added stacktrace_frame.object_address

What's new:

• Cpptrace now has a C API! 🎉
• Cpptrace is now able to parse macOS debug maps and resolve stack traces without dSYM files

Most notable improvements:

• Updated cpptrace exception objects to generate traces at the callsite for improved consistency with trace output. As part fo this cpptrace exception objects have had their constructors updated.
• Improved dwarf back-end robustness
  • Fallback to the compilation-unit cache or walking compilation-units if aranges lookup fails
• Eliminated reliance on a CMake-generated export header
• Added a configuration to control resolution of inlined function calls
• Made architecture selection in Mach-O universal binaries

Other improvements:

• Improved documentation for installation and usage
• Generally improved README content and organization
• Fixed an MSVC workaround producing dozens of warnings
• Better handle compiler color diagnostic arguments if compiler families differ
• Improvements for handling libdwarf's header placement
• Fixed issue with libunwind resolution
• -Werror is now used in CI
• More library configurations are now tested in CI
• Updated to libdwarf 9
• Updated the library's CMake to acquire zstd through FetchContent
• Fixed minor issue with stacktrace printing always trying to enable virtual terminal processing, even when not actually printing to the terminal.

Pre-release for 0.4.0. Hoping to get that out in the next few days.

Tiny patch:

• Fix CPPTRACE_EXPORT annotations
• Add workaround for msvc bug affecting msvc 19.38.
