When building a unit registry using a cache, the read cache data is not getting leveraged. Instead a new cache is getting built, but without the dimensional equivalents. This creates a behavior where you create a new UnitRegistry from already cached files and call `get_compatible_units` it will always fail with a key error.

I don't think this is a good idea without further thoughts. Basically, I am worried that we might be caching objects which are specific to this registry. Remember that certain objects (Quantity/Unit/Context/Measurement) are registry instance specific and should not be cached. That part of the code is not in use to investigate if this was a good idea or not. |
