Add Sign/Verify of Long type claims

[vrancic]

I added Long type for claims and updated tests.

Hi @vrancic
Thanks for the PR 🎉 ! Before merging it there are a few tests missing I'll need you to add:

• NullClaim: Test that it returns a null Long. (ref)
• JWTVerifier: Test that a Long claim can be set and verified (ref) and test that a Long claim has a different value and the exception is raised (ref).

Check the coverage reports if you need more insight.
Cheers.

Hi @lbalmaceda

All tests are passing now, so I think that this version is ok. If everything is ok, when can I expect the changes to be approved and library added to official maven repository?

@vrancic Thanks for the update. Looks good!
I'll be happy to merge the PR but for consistence I think it should also add a method to set a Long claim in the JWTCreator.Builder. Check this as an example and please add the corresponding tests.
Once approved it can take up to 2 weeks for us to publish it.

Cheers
