Change description:

- Implemented 'plot view' functionality with support of the linear,
point and gantt charts. Gantt charts not operable yet, while the
infrustructure is already prepared.
- Updated README.md
- Updated UML diagrams
- Fixed bug with endless update of the 'grouped view'
- Fixed bug with short disconnection interrupting the continuous search
- Adapted github workflows

----

- Implementation of the 'plot view' was heavily tested on the Linux
- Fixes for bugs were verified to be functional
