Update CCF examples to match latest changes to CDDL and confirm they match CCF Codec #81
Description
Problem
The CDDL section of CCF specs were updated and some of the examples no longer match the updated CDDL.
Suggestion
Update CCF examples in the specs to match the updated definitions in CDDL notation.
Also, add more examples and confirm they are all in sync with CCF Codec (PR 2364) merged to onflow/cadence on April 13, 2023.
