Allow missing values in ComponentArray constructor

[metanoid]

The following construction fails:
ComponentArray(a=1, b=[2, 1, 4, missing], c=[1, 2, 3])

because in utils.jl there is no method for recursive_length(a::Missing)

Thanks for these! Data science things like this are a bit of a blind spot for me, so it's good to have people using them to let me know what doesn't work for those workflows.

As of right now, ComponentArrays will automatically default to Float64 rather than trying to find a bounding type for all the data passed in. To support other types (including type unions with Missing), you can now do ComponentArray{Union{Float64,Missing}}(a=missing, b=[2, 1, 4, 5], c=[1, 2, 3]).

It looks like this fails with ComponentArray{Union{Float64,Missing}}(a=1, b=[2, 1, 4, missing], c=[1, 2, 3]). because I didn't allow heterogeneous array types. Let's keep this open and I'll look into fixing that.

K, it wasn't too bad of a change. Just needed to look for Union{Number, Missing} when making the axes rather than just Number. I'll have to write some more tests for Missing stuff at some point, but for now I'm going to call this good. If you run into any problems with it, feel free to reopen this issue.
