mhosken 7a0c5e1ca2 Add fea generation support (#776)
* First round of adding fea output

No format tests but all test files give reasonable output so far.

* Get existing tests working

* Initial tests that work for fea2fea

* Get more tests working

Bug fixes and re-layout some tests to compare with fea2fea output.
Ranges and name parameters are not optimised yet.

* Handle vertical default values in fea2fea

* Hide fea2fea differences in lookupflags

* No reduce() in py3 so use a for loop
