Optimize query with DataUpdateCoordinator

[Zen3515]

The main goal of this PR is to allows a single query to update multiple sensors at the same time rather than having to send 20 query requests for 20 sensors.

This PR will fix #13 and #7

To summarize here are the list of changes

• Migrate to DataUpdateCoordinator coordinator
• Convert to Asynchronous
• Optimize query, allowing one query to update multiple sensor entities
• Configurable polling rate via update_interval
• Remove unused dependency library

Hey, thanks for your work on this! I'm curious as to if the work on this branch is complete and ready-to-go or not. I'm looking to lower my update interval by quite a bit. If it is ready to go, I'm definitely going to switch over to running your fork.

I believe so, I've been using my fork without any problem ever since.
