[WIP] Reconversion of Numeric Data to String and back to Numbers

[AbhinavChede]

I have made a few trivial edits in the rule.js file to fix the type reconversion of numeric data to String and back to Numbers. These changes allow us to pass in numeric data in Number format without having to convert the data into a String.

@AbhinavChede Thanks for the work! I had time to carefully go over the code. I think that an easier fix would be letting parseAssembly skip formatData and parseFieldType, and directly generate the final data. The two functions were designed to handle tables of variable formats. But an assembly file yields relatively fixed data formats. Therefore we perhaps don't need them.

Let me try to write a pull request to patch the function.
