Crash on empty file upload

[Ezwal]

Using busboy and busboy-body-parser and node major version 7 and above, the application crash when dealing with an empty payload. The error thrown stems from the measure of the piped file buffer length Buffer.byteLength(d, 'binary') (index.js l.51).
The major change to Buffer break the module since d is an empty array it cause the error :
TypeError: "string" must be a string, Buffer, or ArrayBuffer. Retrograding works since the line is working before #18

@Ezwal Thanks for opening this. I'll take a look asap.

@Ezwal Are you able to provide a minimal test case or steps to reproduce, ideally a curl command, that I can use to replicate this. I'm just trying to get an idea of what conditions would cause the payload to be empty, but still cause busboy to trigger a file event.

No problem if not, it'll just speed up the resolution if I don't have to reverse engineer it myself.

Edit: It was easier than I expected.

Fix published at v0.3.1. Let me know if that solves your issues.
