[PHOENIX-3718] Provide user-level documentation for column encoding feature

• Type: Bug

Description

Let's create a new page on our site describing column encoding. I think we should keep it at a very high level, but document when the feature should and should not be used.

A blog with more technical depth on the implementation might be interesting, though. You up for that samarthjain?
