Rework Grammar and Parser
Add proper headless binary construction: Includes basic validation Add Error and Warning structs to Parser Add FileNode pointer getter to Parser Change all `char8_t*` and `const char8_t` to `const char*` in Parser Add Parser move operators and Parser deconstructor Add BufferHandler PIMPL object to Parser Add UTF-8 file Warning to v2script Add proper Grammar value retrieval Add AbstractSyntaxTree for v2script data parser: Has compile-time embedded type information accessible at compile-time and runtime Has Tab-based print functionality Fix wrong environment reference for headless construction in SConstruct Add error retrieval Add BasicCallbackOStreamBuffer for callback streaming Add CallbackStreamBuffer for char Add CallbackWStreamBuffer for wchar_t Add BasicCallbackStream Add CallbackStream for char Add CallbackWStream for wchar_t Add grammar for events and decisions Add event_parse to Parser Add decision_parse to Parser Add .clang-format Ignore dirty lexy module Add CSV parser and grammar: Creates std::vector<csv::LineObject> for a list of lines Add BasicParser and BasicBufferHandler to reduce code reduplication
