Fixes some reported issues

[gfs]

• Fixes reporting linux binaries are unsigned by adding new field to FileSystemObject for executable type. Rule is now restricted to Windows and Mac executable types. (Signature checking for linux binaries is not implemented in ASA).
• Adds ability to filter results from Export Collect by Analysis Result Type (i.e. WARNING, ERROR etc). Specify using comma separated list of the levels you want to be exported.
• Adds option to export collect results which were saved to the database instead of redoing comparison. Note, to GUI Based Analysis is Orders of Magnitude Slower Than CLI #667 this is unlikely to be faster than just doing the normal export.
• Fixes output sarif performance.
