Expose lasso from measured to avoid sibling dependencies

[clux]

Minor ergonomics tweak from POV of users.

If you exposed lasso users would not need to update measured along with lasso in a renovate / dependabot group, and users would likely not need an extra lasso dependency (that they don't remember how got there) in their Cargo.toml.

Reasoning; metrics usage is almost universal, but string interning is not (and it's a semi-complex thing to have to front-load cognitively).
