For stability and reliability recovering after interrupted commection reasons

Major update is out 🎉

__Major changes__:

- __[Deprecated]__ `streams` of `.insert()` method;
- `http` module raplcaed with `fetch` — *As suggested* in `meteor@2.0.0` release and `http` package being deprecated;
- `request-libcurl` replaced with `fetch` — Should fix #781 and similar issues;
- __[removed]__ `file-type` library used to detect file-type (*file's mime-type*) based on "magic numbers". Now mime-type detected from data supplied by browser. __Regresion possible upgrade with care if you rely on mime-type detected after file is fully uploaded to server, this change won't affect mime-type detected on the *Client* before file fully loaded to server__.

__Improved__:

- Pause/Resume logic when connection with server is interrupted (*no more missed chunks*);
- Chunks deliverability, including retries if chunk was sent only partially.
