Extracts parameters from the outermost array node of array (many types supported, including all Awkward Arrays and Records).

Parameters are a dict from str to JSON-like objects, usually strings. Every ak.layout.Content node has a different set of parameters. Some key names are special, such as "__record__" and "__array__" that name particular records and arrays as capable of supporting special behaviors.

See ak.Array and ak.behavior for a more complete description of behaviors.
