Output higher-level report from scsimon (#596)

Browse Source 
* Output JSON file for post-processing

* Debug utility for parsing the SCSI data

* Prototype app for parsing scsi captures

* correct arg parsing

* output html

* Cleanupt html output

* Add missing include

* Allow compilation on non-Linux platforms

* Refactored scsimon to be in multiple files

* Refactored away

* Restructured scsimon into smaller pieces

* Added ability to read in pre-generated .json file and re-parse it

* Delete scsiparse.cpp

* Fix argument parsing and code cleanup

* Ran vscode c++ formatting utility

* Restore the -Wno-psabi flag for Linux only

* Address compiler warnings

* Updated to use C++ style ostreams

* Cleanup conversion to c++ style ostreams

* Updated to use ofstream instead of fprintf

* Delete src/raspberrypi/scsimon directory
