bad temp dir

[rolfn]

The temporary output directory is created inside the parse function and relative to __dirname. This is a bad idea. At this point of execution __dirname is something like ".../node_modules/gammalatex/". It's not sure if this directory is writable. I suggest to use as default temp dir the content of process.env['TMPDIR'] with fall back to "/tmp". And additional: Make the temp dir configurable. Thanks.

Pull request #4 made the temp dir configurable.

From the comments on that PR, @rolfn requested:

In addition: I would like to have a switch (e.g. "keep:true") to indicate that the temp dir will not be removed after the LaTeX run (for debugging).
