Decimal floats not folding

[danielfomin96]

Hello,

Firstly, thank you very much for this project. After starting to work with your extension, I don't think I can ever write monkey C without it again.

Upon inspection of the optimized code I found that literal expressions that contain floats in decimal form do not fold. Is this known or even anticipated? Since floats are used in many projects and probably have a great impact on the performance of the program this feature would be well received.

Example:

        function test(){
            const t = 10;
            const fl = 0.5;
            const c = 5;

            var test1 = t * fl * c;
            var test2 = t * c * fl;

            return test1 + test2;
        }
---------------------------------------------------
Optimized to:
    function test() {
      var test1 = 10 * 0.5 * 5;
      var test2 = 50 * 0.5;

      return test1 + test2;
    }
----------------------------------------------------
Expected:
    function test() {
      var test1 = 25;
      var test2 = 25;

      return test1 + test2;
    }

I was just a little conservative when I first wrote the constant folding code. It also turns out that none of my projects have any examples of this, so I've never been motivated to go back and fix it!

But yes, should be fairly straightforward. I'll try to get it into the next release.
