Crate cache_cache

This caching library has been designed for specific use-cases where:

• getting a “fresh” value can be time consuming and can fail (eg. IOs with hardware)
• getting multiple values at once can be more efficient than getting each value independantly.

Typically, its primary use was to retrieve position/speed/temperature/etc from multiple motors using serial communication. In this setup, the motors are daisy chained, and in the protocol used to communicate with them, a specific message can be used to retrieve a register value for multiple motors at once.
