Fix typos method and parameter

[bact]

• enum: Unkown -> Unknown
• method: getCaseSensisitiveId -> getCaseSensitiveId
  • parameter: caseInsensisitiveId -> caseInsensitiveId
• Add default method getCaseSensisitiveId with the same parameter spelling caseInsensisitiveId for backward compatibility
  • This default method is implemented inside the interface, so it will be available to any class implements the interface without the need to actually implemented it (to avoid breaking)

Note: as the enum and the method are public, this change will break any code that use any of them

Method getCaseSensisitiveId is still available and can be called the same way.

Defer the renaming of enum for now, just add a comment to the code.

If this change is accepted, further updates of names are needed in https://github.com/spdx/Spdx-Java-Library

I'm concerned about the breaking changes to the public methods - so I'll label this for the next major release.

@goneall I have removed the enum renaming and add the default method to the interface (per discussion here: spdx/Spdx-Java-Library#266 (comment) ) - will this address the backward compatibility concern?

Also deferring the enum renaming.

Looks like this should work - I'll go ahead and approve / merge in. If it turns out to break something downstream, we can fix it before the next release.
