feat(bin): override package locations using repeatable --source options

BREAKING CHANGE:
Previously the location of package.json files could be overridden like so:

```
syncpack list './package.json' './packages/*/package.json'
```

This is now done using a repeatable `--source` option:

```
syncpack list --source './package.json' --source './packages/*/package.json'
```

This change is to make way for new commands which will also require an
overridable `--target` option.
