Hi, i have taken a look at this PR so here is few feedback.

• it's nice to be able to write TS directly.
• Also now we can directly import the functions, without need to construct first the module ("_npyjs = new npyjs()"). That's much simpler and convenient.

On my side TS was complaining about few things so i have patched the following: 3215e46 37262c9.

The only problem i have is with the merge of parse and load.
Now there is a single function load. This mix the previous parse which was a pure no IO, and the previous load which was doing the IO.
So now, even if you just want to parse, you depend on an async function, while it's not the nature of such function.

Another small thing, also related to load function.

It tries to support multiple input types

• string as an URL -> to fetch it
• ArrayBuffer -> like before for parse function
• TypedArray -> to get the buffer of the array

A typed array have a specific location and size in an array buffer.
When it get the buf = source.buffer it lose such information. In the following code it will read the wrong location in the buffer.
Offset=0 is most probably always the case in your use cases. But it would be safer to throw an error if the offset from the typed array is not 0.

Thank you @vallsv and @sebaB003 for contributions on this one!! I need to take a look at why tests are failing, probably this weekend... if either of you want to work that problem out before then, I will merge it and make this the latest tagged version once it's working!!

This should be working on #57
