Unnecessary dependency on protocol-buffers

[pakoito]

Reported by /u/Magillus:

Problem: method count padded by 6k by protocol buffers
http://www.methodscount.com/?lib=com.github.pakoito%3ARxObservableDiskCache%3A1.0.0

Solutions:
It just doesn't work as expected so I've open an issue in their repo magro/kryo-serializers#59.

Alternatively, I've created a PR for PaperDb pilgr/Paper#54 to use a fork of the serialisers while the problem is being solved.

Update:

Kryo-serializers has updated to remove the unnecessary dependency. If you're in a hurry, add version 0.39 explicitly to your build.gradle: https://github.com/magro/kryo-serializers/releases/tag/kryo-serializers-0.39

For everyone else, there has been a major update for kryo 4.0 and and kyro-serializers has updated to it, so https://github.com/magro/kryo-serializers/releases/tag/kryo-serializers-0.40 is available now. PaperDb is also updating to this version, and is currently in RC status: https://github.com/pilgr/Paper/releases/tag/2.0-rc1

As soon as PaperDb updates I'll update RxPaper too.

Hopefully I will be able to tackle this by next weekend. If I haven't in more than 2 weeks and you're reading this, please @ remind me.
