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
