hactoolnet: Tweak NCA processing

Browse source 
- Ignore the relevant --section#(dir) option if the equivalent --exefs(dir) or --romfs(dir) option is set
- Display a warning instead of completely erroring when trying to extract a section that doesn't exist
- Fix an off-by-one error that resulted in section 3 not being extracted. In practice this hasn't mattered much up to this point because no official NCAs contain a section 3.
