Blender add-on: BIS v. 1.9.0.

Updated some parameters for Blender 2.83 nodes
The format of data storage in the library has been changed. Now the backward compatibility is fully supported, saved materials, and node groups for any previous versions can be loaded with the add-on version 1.9.0. In the future, it is planned to update all materials and node groups in the repository to version 1.9.0. After that, backward compatibility with older versions will be removed from the add-on. Users can update their materials themselves by downloading the material from the repository and updating it by clicking the “update” button. It is not necessary to do this; in the future, all non-updated materials will be updated to version 1.9.0. automatically.
A code refactoring was made, now more attributes are saved for each node. Getting of the attributes is now automatic.
The size of the saved data is reduced due to archiving on the fly, which should reduce the amount of traffic when working with the add-on.
