add maxBuffer configuration

[msalahat]

There are some apk files that are larger than the hardcoded maxBuffer size [ 1024*1204 ] which creates a need to have it as an option .

Good fix. Let's ignore the 0.8 failure, who cares about that these days? :-)

Merging + releasing.

Published version 0.1.1 to npm

@rubenv Maybe you need to modify the documentation as well to mention maxBuffer configuration
