python(feat): Adds batch rule update/create support to sift_client

[tsift]

Adds higher-level support for the "batch update rules" API which can be used to both update and create rules. Additionally updates "create rule" to utilize the new batch API.

[tsift]

Additional verification from local testing showing the batch method approximately 10x better than with the previous "create_rule" workflow.
