Whistle Option Request

[JasperHuskyFox]

I would personally like if we had the option to switch between the whistle types. I like the normal mode whistle the most, but I want to use it in the hell mode. And I would guess some would like the Hell whistle in Normal mode too. Im not sure if the whistle sound difference is hard-coded due to the mode differences, but if it isnt, I would love a way to change between the two options.

Maybe in a future a whistle note customisor? But thats an idea for a "what if" kinda thing
