v2.0.0

This release brings an entirely new annotation resolution engine which
is backwards-incompatible with v1.

New features include:

1. typic.protocol for binding a serialization & deserialization
   for any type or annotation.
2. @typic.constrained for definining restricted versions of
   builtin types.
3. @typic.settings for resolving the default values of a dataclass
   from your environment variables
4. A whole new suite of useful types, including:
   • FrozenDict, a hashable, immutable dictionary
   • DSN, a JSON-serializable string-type for your database URIs
   • URL, a JSON-serializable string-type for your URLs
   • Email, a JSON-serializable string-type for emails
   • SecretString, a JSON-serializable string-type for hiding
     secrets when logging or printing
5. typic.schema for getting a valid JSON Schema definition for
   your classes and type annotations. typical classes also have
   access to this as a classmethod.
6. typic.primitive for extracting a valid JSON-serializable
   primitive from just about anything. typical classes also have
   access to this as an instance method.
7. typic.tojson for dumping any value directly to a JSON-compliant string.

And so much more. Check out the documentation for details!
