directive features needed

[mindon]

feature 1: keep import as it is

// emit-ignore
import * as hello from "https://hello.cdn.dev/hello.js";

feature 2: bundle import url as a local module js optional with specified path (default ./) and name (default as original name)

// emit-module=./a-path/a-module-name.js
import * as hello from "https://hello.cdn.dev/hello.js";

a md5 key would be in the final js or ts file name, and the import code changed to a // emit-ignore directive replacement

// emit-ignore
import * as hello from "./another_path/a_new_module_name-##md5key##.js";

these will be practical useful (implemented in a modified version of packup - which is using esbuild)

btw, it's more simple and clear beside the import code than a extra configuration.
