extra instances

[infinity0]

Hi, thanks for creating this package. I needed some extra instances so I went ahead and defined them and uploaded it to hackage: https://hackage.haskell.org/package/wide-word-instances-0.1

If you'd like to merge those into this repo or co-maintain them or something, just let me know, I will be happy to add you to the hackage owners group.

I can't see any good reason why these instances should not be provided by wide-word itself. Please submit a PR.

I was thinking it might be good to try to have this added to GHC base libraries, e.g. like how rust provides 128 and 256-bit integers. In this case, these instances would have to go in their respective packages binary and serialise.

I think Binary belongs to wide-word (See also #50). serialize OTOH starts to be a heavier package, so it makes more sense for serialise to depend on wide-word, and I don't see a reason why it wouldn't.

To clarify my stance on serialise instances.

I'm considering adding wide-word dependency to e.g. aeson. But if there is even a slightest chance (or risk) that wide-word would depend on serialise, then I cannot afford that.

The current dependency footprint of wide-word is acceptable, but depending on libraries which itself depend on a lot of packages (like serialise is a batteries-included one depending on plenty of small type providing libs) won't be.

I will not be adding serialise instances to wide-word.

The binary instance is here: #78
