Summary

Introduce a quicker algorithm if applicable.

Detail

BEFORE: running sparo checkout --to <package_name> always internally invoking rush list to get a full functionality of getting target folders by selection parameters from Rush.js.

AFTER: if running sparo checkout --to/--from with named package only, a new algorithm will be opted-in to avoid the time to preparation the local Rush.js. That says that the new algorithm doesn't need to bootstrap local Rush.js which save some time.

Some cases:

sparo checkout --to foo --from bar opt in sparo checkout --to subspace:subspace_name fallback to rush list sparo checkout --to tag:tag_name fallback to rush list
