This PR adds support for SONATA point-process cells.

Point-process cells are instantiated from SONATA model_type = "point_process" and model_template, mapping directly to NEURON point mechanisms defined in HOC/MOD files.

What is included

  • New HocPointProcessCell for SONATA point-process populations
  • Mechanism instantiation driven by model_template (e.g. nrn:IntFire1, hoc:)
  • Integration with CircuitSimulation (instantiate_gids, callbacks, deletion)
  • Spike detection and recording compatible with existing simulation flow
  • Support for SONATA inputs and SynapseReplay via _add_stimuli
  • Compatibility with SONATA edge loading through existing SonataCircuitAccess

The logic for loading from sonata files is to swap out the list of parameters if the BBP TYPE is not present

Likewise, when instantiating a synapse object, if no TYPE field is present, assume it is for allen and
create a Exp2Syn synapse
