Add parsing dimensions, exception and refactor to stats converter.

- Atom fields that are encoded in dimension values are decoded and
converted to PersistableBundle formats
- Throw new StatsConversionException when there are atom fields mismatch
or malformed dimension values
- Changed the way atom data converters are implemented. New converters
can simply extend the AbstractAtomDataConverter class. It just needs to
provide a atom field parser which has all the atom fields metadata
and actions in one place.

Native (C++) code format is required to be compatible with .clang-format file. Run

git clang-format --style=file --extension='h,cpp,cc' HEAD~

Note that clang-format is not desirable for Android java files. Therefore the command line above is limited to specific extensions.
