Encode & Decode anything as root

[Chuckame]

Issue

Currently, we are only able of encoding and decoding records as root, but we cannot encode and decode primitive values, arrays, or maps.

Proposal

Be able of encoding and decoding (and generating the associated schema) for any type of value:

• record
• union (not only with records)
• enums
• primitives (boolean, int, long, float/double, enum, string, bytes, null)
• fixed
