Daniel/cleanup unused code

[dadukhankevin]

Removed many unused/old files, combined tiny utilities that go together, removed commented out code blocks, converted large .ts files to json, this is faster and more space efficient.

we don't need this anymore

@BenjaminScholtens Do we need the file?
(ln 122-123)

                    words.forEach((word: string, idx: number) => {
                        const cleanedWord = cleanWord(word);

because the function itself is used later, but if we don't need the file, we can just delete all of it?
