A user defined operation that is injected with other p-code.
The system can configure user defined p-code ops as a hook point within the control-flow where other p-code is injected during analysis. This class maps the raw CALLOTHER p-code op, via its constant id, to its injection object. The injection object is also referenced by an id and is managed by PcodeInjectLibrary.
