Decoupling umati dashboard Location-Requirement from machine

[PaBer89]

https://github.com/umati/Showcase/blob/main/Dashboard.md defines the Identification Location property as requirement for a Fair assignement and to get a pin on the dashboard map.

On the other hand, neither https://reference.opcfoundation.org/Machinery/v104/docs/8 nor https://reference.opcfoundation.org/DI/v105/docs/4.5.2 defines this as mandatory. This means that umati relies on the presense of an optional element or the machine software has to be expanded only for showcases and, depending on the circumstances, even adapted repeatedly (if the same machine is used at different locations/fairs).

A more scalable solution for the umati-context would be, that the umatiGateway adds this Location information if not provided by the machine (not available in address space or if value is empty). Defining this within the config-file would increase the flexibility, based on the unique ProductInstanceUri (e.g. for a given ProductInstanceUri the defined Location will be used/added).

That sounds like an interesting idea.
@GoetzGoerisch What do you think?

Looks like good improvement.
