Incorrect handling of non-utf8 data

[thejh]

As it seems, snappy converts input to strings before it actually handles it which can completely destroy your data:

> new Buffer(new Buffer([255]).toString())
<Buffer ef bf bd>
> snappy.compressSync(new Buffer([255]), function(err,data){gerr=err;gdata=data})
> gdata
<Buffer 03 08 ef bf bd>
> snappy.compressSync(new Buffer([255]), function(err,data){gerr=err;gdata=data})
> gdata
<Buffer 03 08 ef bf bd>
> snappy.compressSync(new Buffer([0xef,0xbf,0xbd]), function(err,data){gerr=err;gdata=data})
> gdata
<Buffer 03 08 ef bf bd>

Same applies for uncompressing.

Hi!

Thanks for the bug report!

I've reproduced the error that you're describing. I'll try to sort it out and add a test case for the behavior later on.
Stay tuned.
