PrintMojo should allow users to convert floats to doubles

[exalate-issue-sync]

Predictions and split values outputted in JSON from PrintMojo are java Floats. However, JSON doesn't preserve type information and without paying extra attention to the issue the parser might interpret the values as Doubles. This would lead in a difference in the prediction based on the json interpreted code and POJO/MOJO/H2O.

To mitigate that we should add an option (--floattodouble) to output Doubles instead of Floats and thus prevent possible parsing issues.

example:

java -cp genmodel.jar hex.genmodel.tools.PrintMojo -i gbm.mojo -o gbm.json --format json --floattodouble
