v2023.8.0-beta1

First public beta of the "2.0" version of Smart Irrigation. New features:

• configuration panel
• multi-zone support
• multi calculation modules support
• mappings: mapping data from multiple sources to zones

Keep in mind that docs are non-existent at this point, except one Wikipage. Also, there is no migration from version 1 to version 2, so please back up your configuration before installing this version in case you need to go back.
