serde_json_pythonic

serde_json fork that includes a Pythonic JSON formatter, which mimics output from the json.dumps() function in Python.

While it's indeed possible to create such a formatter without modifying serde_json, it only works when the std feature is enabled, as serde_json does not expose the types needed for the formatter implementation under no_std mode. This fork makes such a formatter built-in and also available in no_std.
