Feature request: add a CLI API

[aduh95]

What problem would this feature solve?

I'm looking for a replacement for deno bundle which has been deprecated. Having a CLI way to call the method would be ideal for a drop-in replacement for someone who wants to use the defaults.

What would this feature look like?

Something like:

$ deno -A run https://deno.land/x/emit/cli.ts --bundle ./entryPoint.ts > bundle.ts

💯 This seems kind of essential before dropping support for the deno bundle command line interface. Is this planned but on hold until the API stabilizes, or something? Is there something wrong with the bundle example? Just curious as to what to expect, since I've been informally relying on bundle.
