feat: add NewDocumentFromReaderWithOptions

goquery calls html.Parse, so callers cannot reach the parse options that
golang.org/x/net/html has since grown. The one that matters is
ParseOptionEnableScripting(false): with scripting assumed enabled the
contents of a noscript element are parsed as raw text and no selector
can reach inside it.

Add a constructor taking html.ParseOption values. Existing constructors
are untouched.
