Warning when loading the model in urdfdom-py

[traversaro]

Running the example in https://github.com/ami-iit/ADAM#jax-interface results in a lot of warnings:

Unknown tag "sensor" in /robot[@name='iCub']
Unknown tag "sensor" in /robot[@name='iCub']
Unknown tag "sensor" in /robot[@name='iCub']
Unknown tag "sensor" in /robot[@name='iCub']
Unknown tag "sensor" in /robot[@name='iCub']
Unknown tag "sensor" in /robot[@name='iCub']
Unknown tag "sensor" in /robot[@name='iCub']
Unknown tag "sensor" in /robot[@name='iCub']
Unknown tag "sensor" in /robot[@name='iCub']
Unknown tag "sensor" in /robot[@name='iCub']

Probably this is urdfdom-py related?

Let's use this discussion to understand if there is anything we can do to fix this.
