Feature/async incremental

I've included a simple script I used for testing.

It would be nice to have a test suite for this library

This looks like it would be better handled by purescript-nullable. Then we wouldn't need to import two different versions using the FFI. Same for writeSeq. @garyb does that sound ok? Adding this as a dependency, I mean.

[garyb]

You mean so there's just read, and then we use toNullable on pos? Sounds good to me, that's one of the motivating use cases for it.

[hdgarrood]

Yes, exactly.

[hdgarrood]

Oh, that reminds me, we should be using ^0.2.0 of node-buffer.

[hdgarrood]

Actually don't worry about this, I'll take care of it later.

[hdgarrood]

Great, thanks very much! I just have a couple of tweaks that I want to do before I release this.

I just have a couple of tweaks that I want to do before I release this.

Will this include adding the new Buffer effect type to the signature of the relevant functions in this package?

Yesterday I wrote code that looks like this:

do
      let buf = create size
      fdNext fd buf
      pure buf

which makes me unhappy.

[hdgarrood]

Yes. Also, one of those tweaks is updating to node-buffer ^0.2.0, where create returns an Eff action instead of being a pure function (which is a lie).
