feat: add very basic syntax highlighting

[MaartenS11]

Currently just splits the string in 2 so the arguments have a different colour than the opcode but this does mean that things like commas are also highlighted.

Result:

Or in light mode(carefully placed in a spoiler):

Or dark mode with the seedColor=Color.Green

@MaartenS11 I haven't jet written any docs but we use ktlint. I recommend you install the intellij plugin, and there is a pre-commit hook that you can install that will automatically format any staged files. (Not sure if it gets automatically installed on gradle sync)

Suggestion: split the instruction string on spaces and then color all elements that are not the first element.
