Include time-literals library for whole project

[ezmiller]

We will eventually avoid using the tick library we think. That said, we probably do want to make use of the time-literals that tick bundles: https://github.com/henryw374/time-literals.

We probably want to make this available across the library. We might be able to learn how to do this from tick, see this namespace: https://github.com/juxt/tick/blob/master/src/tick/time_literals.clj
