Refactoring round 1

[NikolajSchlej]

• introduce Extract Uncompressed and Uncompressed Hex View actions for compressed items, fixes UEFITool NE - Extract <file|body> uncompressed #150
• add a check and description for section alignment quirk (compiled out for now), will help fixing Detect out-of-spec size requirement for some FFS sections #178 later
• remove unused code to support Qt 5.5 and earlier Qt versions
• remove unused section parsing code

Turns out that windows-2016 runner is now deprecated for good, and we need to update the Windows CI setup for it to start working again instead of hanging in Queued state forever.
