refactor: ♻️ Completed codesplit and typescript refactor

Refactored all code to improve readability as plugin development continues. Typescript types were added to all variables, including any `parts` modules to improve intellisense while developing. Function overloads and jsdoc comments were added for similar reasons. This refactor also included improvements to tag processing by implementing tag processing completely through observables with custom pipes.
