Support for freespace parameter in OSC2.0

Support for ‘freespace’ parameter in longitudinal & lateral distance based actions & conditions

No equivalent to specify freespace parameter. No provision to define a way to measure the distance. For example - distance between bounding boxes or origins.

When migrating to OSC 2.0, we need to either ignore this parameter or use extended action to cover unsupported parameters which might be difficult for interoperability.
