PEL: Look for callouts in an FFDC JSON file
The PEL constructor takes a list of files that should be added as
UserData sections for FFDC. If one of those files has its format set to
JSON, and its subtype set to 0xCA, this will mean it contains a JSON
array of callouts to add to the PEL.
This commit will look for that type and subtype, and then pass the
callout JSON through to the SRC class. A future commit will add the
callouts from the JSON to the PEL.
