[PTI-SDK] Increment Version and set SOVERSION (#35)

* Increment SDK version to 0.2.0
* Add minor version to SOVERSION/SONAME to denote compatibility between
  versions. This will eventually change back to major version after
  `>= 1.0.0` release.
* Added warnings for when this eventually changes back.
