Custom dimension length is hard coded to 20 when it allows up to 50

[falz]

tagging.py is hard coded to 20:

• https://github.com/kentik/kentikapi-py/blob/2b759b021c6acca981736f99e75479ec8ffca7cf/kentikapi/v5/tagging.py#L438C1-L439C1

        if len(column_name) < 3 or len(column_name) > 20:
            raise ValueError('Invalid value "%s": must be between 3-20 characters' % column_name)

While in the portal it allows up to 50:

Additional note: the docs say this field is 30 chars max:

• https://kb.kentik.com/v0/Ec07.htm#Ec07-Custom_Dimension_Create

So:

1. Python API script limits to 20
2. Web UI limits to 50
3. API docs say 30
4. unknown what actual API limits to

Re item 4 - that API link above says 'test it with API tester' but I cannot find custom dimensions there to test/find out.
