Summary:
Modified `Entity` to use the new `ResolvedVal` data type. Other changes follow naturally. Related issues: https://github.com/facebook/duckling/issues/121 and https://github.com/facebook/duckling/issues/172
Now one can pattern match on the output value, for instance:
```
{-# LANGUAGE GADTs #-}
import Data.Text
import Duckling.Core
import Duckling.Testing.Types
import qualified Duckling.PhoneNumber.Types as PN
parsePhoneNumber :: Text -> Text
parsePhoneNumber input =
case value entity of
(RVal PhoneNumber (PN.PhoneNumberValue v)) -> v
where
(entity:_) = parse input testContext testOptions [This PhoneNumber]
```

Summary:
Return the canonical holiday name if the input had a holiday in it and the date resolves to the date of the holiday.
Add `holiday` to `TimeData`.
Set it in the holiday rule.
Make sure it propogates appropriately in `predNth` and `intersect`.
Make sure it doesn't propogate in other rules.
Add `holiday` to `TimeValue` and set it during `resolve`
