Add support for larger files

[phun-ky]

I had an issue with generating a file that was 12mb (others under 12mb worked fine). Kept getting this error:

maxMemoryUsageInMB limit exceeded by at least ${exceededAmount}MB

Is it possible to support larger size images as an option? Only way to circumvent this is to heavily either scale down the original image or to reduce the quality too low..

Sure, looks like a pretty straightforward fix, as the issue is in jimp: jimp-dev/jimp#915

Just released version 0.0.20, let me know if that works for you!

Closing because of inactivity, please let me know if there are any other issues!

@dkaoster thanks for fixing the issue. I circumvented this for my usage, but this is appreciated none the less <3 Keep up the good work!
