Summary:
Whle looking into fixing https://github.com/facebook/duckling/issues/380
I was having a bit of trouble navigating the existing rules and guessing
what is / is not supported.
This diff refactors the Numeral/ES code to be easier to navigate:
- rename all the `ruleNumeral{1,2,3,4,5,6}` rules to be descriptive
- changes the order to be themed from small to large numbers, and
make sure the order of defines matches the order of rules at the end
of the module
- use [20 .. 90] instead of manually specifying the same list out-of-order
