Use the new Buffer APIs from Node v6 for added security. For example,
`Buffer.from()` will throw if passed a number, unlike `Buffer()` which
allocated UNINITIALIZED memory in that case.
Use the `safe-buffer` package for compatibility with previous versions
of
Node.js, including v4.x, v0.12, and v0.10.

To use the client, you used to pass in four arguments:
`new Client(peerId, port, parsedTorrent, opts)`
Now, passing in the torrent is no longer required, just the `announce`
and `infoHash` properties. This decouples this package from
`parse-torrent`.
All options get passed in together now:
new Client({
infoHash: '', // hex string or Buffer
peerId: '', // hex string or Buffer
announce: [], // list of tracker server urls
port: 6881 // torrent client port, (in browser, optional)
})
All the normal optional arguments (rtcConfig, wrtc, etc.) can still be
passed in with the rest of these options.
Fixes#118. Fixes#115.
Added ws tests for scrape.
Before this fix, udp tracker urls needed to contain “/announce” or else
we would assume the tracker doesn’t support scrape. (This is correct
behavior for http trackers, but not udp)
