Make `User.discriminator` a u16

Change the User struct's `discriminator` field to a u16 for performance.

The User struct's `discriminator` field was previously a u16 but changed
to a `String` for ease-of-use. Lately the library has been gearing more
towards performance where possible while not sacrificing ergonomics
_too much_ in most scenarios.
