Add "Take this sequence modulo n" command

Now the sequences are manually written by user, this feature will allow to use arbitrary growing sequences (e.g. from OEIS) without breaking out of hearing range.

Example:
Ulam sequence under 100 taken from internet and taken modulo 13 in BP.

Hi, I'm considering adding a feature for users to add javascript to programatically generate tunes rather than having to type them, which could definitely do something like this and much more. I'd like to keep the xenpaper grammar itself as 1:1 to how it is played as possible.

I've added #31 to note down the generative code idea I mentioned.

It's even better, thank you!
