First Stable Release

This is bic's first stable release. There have been some major changes since v0.9.1, including:

• Rewrite of the parser to make it C11 standard compliant.
• Add offical MacOS support and CI.
• Add official aarch64 support and CI.
• Rewrite the cfile subsystem of bic to cscript, allowing for c-looking scripts that don't require main().
• Forward arguments from bic's command line to the main() function being interpreted.
• Add a startup file for the REPL, ~/.bic that's interpreted each time the REPL is invoked.
• Allow the AST to be printed out in graphviz's dot format so it can be easily visualized.
• Various bug fixes in the evaluator.
• Make the compiler use -Wall by default and cleanup the resulting warnings.

As always, if any issues are encountered, feel free to raise an issue. Enjoy!
