Remappable peripheral pins

[hasn0life]

Hello and thank you for making this wonderful language.

I was wondering if it would be possible to allow the I2Cs and UARTs to do pin remapping on the ESP32 since it supports it. I don't know what a good interface would look like tho, would it be another function or more arguments or optional arguments? Right now I'm modifying the codebase to do it, but maybe that's the best way?
