feat: add id to RtcDataChannel bindings

[DougAnderson444]

wasm-bindgen/crates/web-sys/src/features/gen_RtcDataChannel.rs

Line 21 in b76af3b

pub fn label(this: &RtcDataChannel) -> String;

I see label is here, could we also add the id property to RtcDataChannel ?

Yes, this is quite straightforward to accomplish, see the wasm-bindgen Book on how to do just that.
Let me know if you need any help.

[DougAnderson444]

Excellent direction, thanks I'll do that.
I take it since the id is between 0 and 65,534 would be an unsigned long?

readonly attribute unsigned long id;

I didn't see the definition for the difference between unsigned long and unsigned short anywhere

[DougAnderson444]

I figured out that unsigned short compiles to u16 which is the 65,534 we need
