Descriptors cannot be created directly

[jshn9515]

When I try to import siphon.cdmr.dataset, I receive this error:

TypeError: Descriptors cannot be created directly.
If this call came from a _pb2.py file, your generated code is out of date and must be regenerated with protoc >= 3.19.0.
If you cannot immediately regenerate your protos, some other possible workarounds are:
 1. Downgrade the protobuf package to 3.20.x or lower.
 2. Set PROTOCOL_BUFFERS_PYTHON_IMPLEMENTATION=python (but this will use pure-Python parsing and will be much slower).

More information: https://developers.google.com/protocol-buffers/docs/news/2022-05-06#python-updates

My protobuf package is 4.25.2.
It can be fixed by either downgrading the protobuf package to 3.20.0 or adding these codes before the import statement:

import google.protobuf.internal.api_implementation as api
api._implementation_type = 'python'

import siphon.cdmr.dataset as dataset  # now everything works fine.

But according to protobuf docs, this API is not recommend to use.
