Reduce compiled size again

[aantron]

See #54 (comment). It is currently a bit under 4K over 1K (thanks @cknitt), up from an earlier ~950 bytes, but, per the linked comment, there is likely a lot of the new stuff that can be easily reduced.

Also, the Promise.allOk code uses the Array module from the OCaml stdlib, so that the compiled code imports both

var Belt_Array = require("bs-platform/lib/js/belt_Array.js");
var Caml_array = require("bs-platform/lib/js/caml_array.js");

I think it would be better to use Belt everywhere.

Thanks, good catch. I chose Array for this initial version so I could write the same code for native and JS in limited time :) I'll solve this issue in a week or two and do a follow-on release.

After #58 by @cknitt replaced Array fully by Belt.Array, the compiled size is 1184 bytes

The above commit further reduced the compiled size, to 1099 bytes. This version of the library is now in npm as reason-promise@1.1.1.

As an interesting factoid, when it comes to the source size, 60% of the published npm package is the library README :)
