Helper function for a val to get its own ID.

Create val
import { getMyValId } from "https://esm.town/v/stevekrouse/getMyValId"

await getMyValId(import.meta.url)

Works even if the val is private if you provide a Val Town API token for the account that owns the private val in question.

Below the Val Town SDK is implicitly authenticated, because it pulls user's Val Town API token from their default 'valtown' environment variable.
