Infer outputtype by Base.return_types

[felixcremer]

This should make broadcasting mixed type arrays much more robust. I had the problem that when I broadcasted two YAXArrays with Union{Missing, UInt8} the outtype was determined as Missing and then the actual results where not able to be written into the Array.

I added a test for such a case.

I am wondering whether we should also make this the default for xmap outtypes in general.

I don't understand why this change is not hit by codecov

[felixcremer]

I found it, we didn't include the broadcast tests. They are now enabled.

@felixcremer ? merge? or do we still want?

However, a quick test for something a function like f(x) = rand() > 0.5 ? Float64(1) : Float32(1) and then f.(cube) would be nice to add.

is this related to #540 ?

No, this was a user error on my part and we could ease this a bit with a better error message.
