Communication Explorer: Control blocks with the same name are aggregated

[danyill]

Currently, the Communication Explorer aggregates control blocks with the same name.
However IEC 61850-6 Ed 2.1 only requires control blocks to be unique within each LLN0 (logical device).

This plugin should identify them using the path (typically we do this using the identity string in many OpenSCD plugins) or calculate an object reference (IEC 61850-6, Section 8.5.2) to avoid doing this.

In this screenshot, it would be tempting to think that there is one GOOSE message, named "Ctrl" which is sent:

In fact, there is three different GOOSE messages, each with a different DataSet:

Here is a test file:

XAT_Subsystem_Testing_Dup_Ctrl_Block_Name.scd.zip

This likely applies to other control blocks but I haven't looked into these further.
