Create generic serializer deserializer for parsers

[TShapinsky]

Create serializer and deserialize functions for Parsers.

Changes in serialized structure:

• name becomes parser
• tokens are now a dict with key token and optional token value. This allows for a instanced or constructor token to be created.

Some performance profiling was done:

• deserialization of common abbreviations takes 0.2ms on my machine.
• tests (copy of existing parser tests with deserialize(serialize(...)) added as a wrapper) complete in less than .1 seconds With these numbers I think this is fast enough to allow us to use this generic parser version.

looks good. Can you help me with the rebase? 😅 I can definitely take care of the rebase. 😄
