Feature idea: short hand commands for common composition scenarios

The wac language is a powerful tool that enables essentially any composition scenario. However, there are some common composition scenarios for which we could provide short hand commands to accomplish without the need for a full script.

## Initial Proposal

My initial proposal for the first short hand command would be for a "plug" composition scenario where there are two components, one of which exports a function that mirrors an import of the second component. The first component essentially "plugs" the import hole in the second.

Another way to think about this is as a shorthand for the following wac script:

```
package example:composition;

let plug = new $PLUG {};

let socket = new $SOCKET {
$SOCKET_IMPORT: plug.$PLUG_EXPORT,
};

export socket...;
```

The command would look like the following:

```
wac plug --plug $PLUG#$PLUG_EXPORT --into $SOCKET#$SOCKET_IMPORT
```

### Unanswered questions

The above example assume that the plug has no imports. We could either provide a flag that allows for the resulting component to inherit the imports of the plug or do this be default. I'm not sure how I feel about it either way.
