Reconstruction logic for padding bytes at the end of Reports (only possible for devices without ReportID) (#707)

Browse Source 
-Add reconstruction logic of const padding bytes at the end of a report for devices which don't use ReportIDs
-Enhanced padding logic to distinguish between byte and bit padding.
-Add a new test case for Razer Cobra mouse `1532_00A3_0002_0001` which has a completly con feature report of 90 bytes.
-Modified expected report descriptor reference file `045E_02FF_0005_0001_expected.rpt_desc` to include additional padding bytes.
