[DEV-CON] Streamline _deep_flat_encode & _deep_flat_decode

[blythed]

These functions involve too much logic; they should include fewer if clauses, and outsource
details of the serialization to the implementations.

Hi @blythed, I would like to take this up. As I can see in the superduper/superduper/base/document.py, both _deep_flat_encode & _deep_flat_decode functions are very complex and nested. So, we can create helper functions to handle the encoding of different object types and use those helper functions inside _deep_flat_encode & _deep_flat_decode functions based on the type of the object being encoded.
