support spread operator

[joe-p]

The spread operator will allow for more optimized updates to multiple sequential values in a tuple.

I was just about to create a ticket for this, glad it's already on the radar. I'll just leave this here as an idea of how someone might want to use it, regardless of how strange and weird it might be.

TEALScript:

import { Contract } from "@algorandfoundation/tealscript";

class RemoteCalling extends Contract {
    call(
        app: Application,
        method: byte[4],
        args: bytes[]
    ): void {
        sendAppCall({
            applicationID: app,
            applicationArgs: [
                method,
                ...args
            ]
        });
    }
}
