add support for floating point comparisons

[cgeers]

I ran across this and discovered only integers were supported in comparisons. The specification supports floating point numbers. Simply expand the scope to the Numeric class to validate any number that is comparable.

@trevorrowe any thoughts here?

Sorry for the slow response. The change seems reasonable.

The spec compliance tests are unfortunately quite a bit out of date. They were originally pulled from here: https://github.com/jmespath/jmespath.test/tree/master/tests

Its been long enough that they have drifted quite a bit. My biggest concern is that if/when I update the bundled compliance tests that your change will be lost and the relevant code fix would not be covered in tests. This would leave us open to a possible future regression. Would it be possible to add another test case, outside of the spec/compliance fixtures to test this case? If so, then I would be very confident to merge your change and to publish an updated release.

no worries. I've added an example outside of spec/compliance.

It's been merged and I'll cut a release shortly. Thanks!
