v3.0.3: fixes for HACS integration

Other fixes for HACS integration. No need to upgrade: if you are at v3.0.1 just don't upgrade.

v3.0.2: minor release for HACS integration

THIS RELEASE IS NOT WORKING.
PLEASE REMAIN AT v3.0.1.

v3.0.1: Connection bugfixes

Several minor connection bugfixes:

• handled responses without a return code
• fixed support for unencrypted clients
• fixed bug when connection fails

v3.0.0: introduction of ASYNCIO and push updates!!

Breaking change in this release!!! v.3.0.0 introduces:

• asyncio in communication, with push updates: now status changes are immediate (also from physical buttons!)
• persistent connection, instead of open-close connection; NOTE: some devices don't support multiple connections, so it will not be possible to use Tuya app together with HA for those devices
• (minor) brightness range remapping for light platform

Enjoy!

v2.0.1: Fixed attributes' DPs and introduced reloading

This release introduces:

1. a fix for 0d-type devices that need optional DPs to be requested (e.g., voltage/current attributes for switches, setPos/getPos DPs for covers...)
2. the service localtuya.reload that can be invoked, and re-reads YAML configuration and restarts all devices

v2.0.0: Total refactoring

This v.2.0.0 is a braking change, which contains a lot of improvements:

• faster communication and status update
• revised YAML file structure
• config flow support
• introduction of sensor and fan platforms

Before upgrading, read carefully the https://github.com/rospogrigio/localtuya-homeassistant/blob/master/README.md file!
YAML config files must be re-written completely!

v1.2.0: autodetection of device type for status commands

Introducing pytuya v7.1.0: this library revision performs an autodetection in order to identify if the device requires the 0a or 0d command for status requests. The previous approach (devices with 20-chars id require 0a, 22-chars require 0d) has proven to be inaccurate.

v1.1.1: reduced logging and caching timeout, removed unused dps

v1.1.1:
Reduced logging and removed unnecessary dps for covers.
Reduced caching timeout to 15s for covers and lights (the same used for switches).

v1.1.0: introduced support for fan; cover commands customizable

v1.1.0:
Introduced support for fan devices, merging from fancygaphtrn (thanks!)
Introduced customizable commands for cover devices and improved README readability, merging from andrewmeepos (thanks!)

v1.0.3: unified dev_type (device20 or device22) handling for all devices

Introduced pytuya 7.0.9: Unified dev_type (device20 or device22) handling for all devices; until now, only switch devices handled it correctly.
