Beta version 1.2.10 Beta 0

CAUTION: This version is not compatible with LOCAL-ONLY-ADDON. Do not upgrade if you use the integration with the meross local addon.

Changes:

• Updated low-level meross_iot python library
• Merged #447

Note: the new version of the low-level library reflects changes recently occurred on the Meross side. In fact, a new authorization API was added and the server HTTPS endpoints were changed. -Both the library and this new version of the component attempt to apply the changes without breaking existing integration, but there's no warranty about that. In case you notice problems with this version of the component, please report it opening a dedicated issue.
