Implement simple client interface compatible with amplify-storage-utils

[joefutrelle]

In amplify-storage-utils there is an abstract base class defining a set of methods for interacting with an object store. Implement a compatible API as a wrapper for a configured client.

https://github.com/WHOIGit/amplify-storage-utils/blob/ec7085dd214913504a0ef0faad6d572045081dec/src/storage/object.py#L10

The use case is a smooth onramp between local development using amplify-storage-utils and use of the media store client--with the same interface in both cases.

As well as the use of these utilities:

That can do caching, mirroring, copying, syncing, and zip compression.

A decision was made to implement this in amplify-storage-utils instead.
