Create package product named `Lazy`

[KyLeggiero]

import Lazy is much more intuitive and descriptive than import LazyContainers when most users will just be using Lazy.

Make this the first in the list, but keep LazyContainers in case some users encounter namespace issues.

This will not require a major version change because the old products will still be around.

Definitely add stuff to the readme to explain that these products are identical, just synonyms
