`as_Array` is broken about purescript-arraybuffer

Thanks for the report.

If you want to enhance the implementation, PRs are welcome. I'm not specially attached to the API either, so if you think something should be some other way we can discuss it.

Also, for other use cases, something like this should be much faster and close to the JS API:

I think that because this package is technically the mainstream package for arraybuffer / typedarray support, because it's published on pursuit, should definitely be at least fully funcitonal - I have a pretty convenient design in mind that's a little higher level than the package you referenced that uses typeclasses for the create mechanism. I'll also have a thorough test suite that proves the consistency of the logic too.

I'm also going to cut the dependency on purescript-text-encoding - encoders and decoders for various implementations should be separate from the actual arraybuffer machinery, plus it's an extra npm dependency for something that could be pure.

I also think the encoding/decoding should be moved to a separate library. There're lots of use cases where you just want binary data. @AlexaDeWit should probably be aware of this... Alexa, could you move that functionality to another library on top?

I might have some time this weekend. I'll take a look.

I agree 100%, and it's already been ripped out. I also want to rip out the Data.ArrayBuffer.Show module - I don't think there should be any npm packages involved, just pure javascript. I also wanted to make arraybuffer-crypto for basic crypto implementations, and arraybuffer-algorithms as a sandbox for sorting algorithms and other cool stuff
