feature: increase user-configurable CBOR limit for MaxArrayElements and MaxMapPairs

[x448]

Is your feature request related to a problem? Please describe.

Current limit of DecOptions.MaxArrayElements and DecOptions.MaxMapPairs is:

• default limit = 131072
• max limit user can set = 134217728

At least one project already set limits to the max allowed. Also, schema-less binary formats like CBOR will be used in large systems and for use cases not initially anticipated.

Describe the solution you'd like

Continue to keep default limits reasonably safe & usable, only increase user-configurable max.

Increase limit of DecOptions.MaxArrayElements and DecOptions.MaxMapPairs to:

• default limit = 131072 (unchanged)
• max limit user can set = 2147483647 (0x7FFFFFFF)

Describe alternatives you've considered

• Ignore this until a user requests an increase.
• Other (smaller) values were too arbitrary compared to the largest positive signed 32-bit int.
