Detailed Description
An injection payload that uses a Ghidra client to generate the p-code ops.
This acts as a placeholder for the actual details of the payload. When the inject() method is invoked, the context is wrapped as XML and sent to the Ghidra client, which returns the actual p-code to inject.

Perform the injection of this payload into data-flow.
P-code operations representing this payload are copied into the controlling analysis context. The provided PcodeEmit object dictates exactly where the PcodeOp and Varnode objects are inserted and to what container. An InjectContext object specifies how placeholder elements become concrete Varnodes in the appropriate context.
- Parameters
-
context is the provided InjectConject object emit is the provovided PcodeEmit object
