Support named tuples and arrow serialization

[haberdashPI]

These two features were pirated in another beacon repo, and are being moved here

I don't think this is breaking?

[haberdashPI]

Based on the slack conversation we do want to be careful about how this is introduced re the pirated methods removed in beacon-biosignals/Onda.jl#126

[haberdashPI]

@ericphanson: I believe this is ready for you to approve.

[haberdashPI]

Though there is some debate over in #42 about whether TimeSpans should support non Period values at all...

[haberdashPI]

Okay. I think that should be safe enough now...

[ericphanson]

Sorry, I don't think I'll get to this by my EOD and I'm out of the rest of the week, so I'll unrequest myself. The version #s and right way to align this with changes to Onda still isn't totally clear to me. E.g. Onda is not compatible with v0.3 of TimeSpans.jl which is a complication here.

Onda is not compatible with v0.3 of TimeSpans.jl which is a complication here

In some ways I think that makes the process a little easier: if we mark this release as breaking then Onda can release a breaking version that requires 0.4 of TimeSpans (skipping 0.3 altogether).

What work is involved in making Onda compatible with newer versions of TimeSpans?

Alternatively, if Onda is not compatible with 0.3 at all, we can just mark this as non-breaking (since the only reason it is technically "breaking" for Onda is that it was pirating some methods that belonged here).

Whenever Onda gets upgraded to support TimeSpans 0.3, it will have to also remove the methods it pirates.

beacon-biosignals/Onda.jl#123

Thanks that's helpful background! Looks like there are a number of moving parts to supporting TimeSpans 0.3 unrelated to the pirated methods. (Annoyingly that probably needs to be fixed for us to benefit from TimeSpans, since Onda is probably a common dependency).
