Added branch location targetting (#767)

* Updated neuron devices to bsb v4
- current clamp, spike generator,  voltage recorder, voltage clamp
- Added LabelTargetting
- Added __lt__ method in TransceiverModel

* Added tags attribute in MorphologyDependencyNode

* Bug fixes.
- Added __lt__ method in TransceiverModel
- NeuronCell instances saves id and positions
- Renamed instance.model to instance.cell_model

* Synapse names are retrived from MechAccessor var

* Added neuron unittests

* Fixed create_transmitters and _allocate_transmitters
- create_transmitters: Now the id of the cells in simdata are mapped through simdata.transmap and the adapter works with multithreads.
-  _allocate_transmitters: fixed gid
- Fixed a report message

* black fix

* test GHA run with dbbs-models

* fix engine references

* fix property assignment

* raise error for using arborize models with missing morphos

* pass on synapse spec weight and delay to `insert_receiver`

* fix

* updated device

* neuron device updates

* removed test configs
