Readme uses deprecated chime/ instead of chime.core/

[lambdaschmied2]

Intellij marks the NS used in the readme examples (at least for chime/periodic-seq) as deprecated.

Should be updated to chime.core/... probably, I think?

Hey @lambdaschmied2 👋

In the first example there's (require '[chime.core :as chime]), which is the standard alias, so these should all run against chime.core?
