Add a count min sketch implementation to the Python code

[simonprickett]

In this repo, we have code that looks at various probabilistic data structures included in Redis and RedisBloom. One that's not part of the demo code is the Count-Min Sketch (https://en.wikipedia.org/wiki/Count%E2%80%93min_sketch).

Enhance the Python code to also count occurrences of each word from Moby Dick in a count-min sketch. You'll want to look at these Redis commands for this: https://redis.io/commands/?name=cms

Where the code outputs information about each data structure at the end, enhance it to use the CMS.QUERY (https://redis.io/commands/cms.query/) command to show the count as stored in the count-min sketch for each of the top 10 words reported by the top-k structure. To do this, you'll need to grab those words from the existing words variable (words = top_k_list[::2]) and feed them into the CMS.QUERY command, then logging the output.

Update the README.md in the python folder, as well as the repo level README.md.
