@public
The storage format of `YGValue` in `YGStyle` is an implementation detail that is going to change soon. It is only guaranteed to be assignable from, and castable to `YGValue`.
Here, we remove tight coupling from the actual implementation in React Native.

When switching to `CompactValue`, casting edges or dimensions to `std::array<YGValue, ...>` will do actual work.
In order to avoid that from happening implicitely, we remove the casting operator.

Enforce more encapsulation of arrays of `YGValue` in `YGSty;e`.

Summary:
@public
`CompactValue` represents a `YGValue` in 32bits instead of 64. This comes at the cost of a range limitation, as one exponent bit is borrowed for the unit.
*Undefined* and *Auto* have no magnitude, and are represented as *NaN* values.
The data structure is meant to be used as a field type on `YGStyle` to save memory.
This is header-only for efficient inlining.

Summary:
I've noticed that when a child's size is determined by `align-items: stretch` in combination with `aspect-ratio` its size is wrongly calculated to account for margin in the main axis when there is more than enough space.
See playground: https://goo.gl/tgW6cD
I've yet to figure out exactly how to solve this but i've started by writing a failing test when can be seen in the first commit here.
I assumed I had found the bug here https://github.com/facebook/yoga/blob/master/yoga/Yoga.cpp#L1838 where margin is being subtracted from the desired width even though the measure mode tells it to measure to exactly that size. However, if we don't remove this margin from the available width then 15 tests fail (including the one I just added) not quite figured out why yet. I'm also a bit confused at to why this would only happen for nodes with `aspect-ratio` and not for nodes where an explicit height and width is set.

`YGFloatOptional::getValue()` has the unfortunate property of calling `std::exit` if the wrapped value is undefined.
That forces `x.isUndefined() ? fallback : x.getValue()` as access pattern.
Here, we replace that by introducing `YGFloatOptional::orElse(float)` which encapsulates that pattern. Other additions are `orElseGet([] { … })` and some extra operators.
