Remove Deno arguments passed by Lume

[oscarotero]

Lume allows to pass arguments to Deno using the -- separator. For example to use the --compact flag for Node compatibilty:

lume -s -- --compact

This feature was introduced before Deno tasks and Deno config file. Now this can be done editing the deno.json config file. So this feature (that is not documented) must be removed.
