Import conversion by ?module uses @latest instead of resolved peerDependency

[natevw]

Preact X's hooks module imports from "preact":

import{options as n}from"preact";

When fetching that with the ?module flag this gets converted to:

import { options as n } from "https://unpkg.com/preact@latest?module";

…which results in broken code, because preact@latest currently redirects to [email protected], and that older version is not at all compatible with the upcoming Preact X hooks implementation.

The package.json for the hooks module specifies:

"peerDependencies": {
  "preact": "^10.0.0-alpha.0"
}

So unpkg should be converting the preact import by specifying preact@^10.0.0-alpha.0 (which currently redirects to [email protected]) for that import, instead of preact@latest.

I mentioned this at #123 (comment) but filing as a separate issue since in this case the peerDependency seems to be getting ignored entirely (despite only specifying a single range).

Is this a dup of #197?

EDIT: Main reason I'm asking is because preact's hooks module uses a nested package.json for resolution, which we don't currently support.

@mjackson Hmm, it may be related i.e. if the reason this is happening is because of the nested package? Otherwise it would be a separate issue related to which version it ends up picking.
