The naming of rewrite-clj.zip/edn is misleading

[lread]

Problem/Opportunity
The rewrite-clj zip API has the non-intuitively and inconsistently named edn and edn* functions.
The functions convert/load rewrite-clj nodes to zippers.
This makes them hard to discover and perhaps confusing.

Proposed Solution
Add aliases that match the existing well-named of-string and of-file: of-node and of-node*.
Deprecate edn and edn* to promote usage of more meaningful named functions.

Alternative Solutions
I can't think of any off-hand.

Additional context
Thanks for @borkdude for the idea!

Action
I'll double-check that these functions really only work with rewrite-clj nodes.
And then I'll follow up with a PR that covers code, docs, and tests.
