Library is using deprecated configuration 'compile'

[wafflekat]

Android studio displays this when I run a project using Compressor:

Configuration 'compile' is obsolete and has been replaced with 'implementation' and 'api'.
It will be removed at the end of 2018. For more information see: http://d.android.com/r/tools/update-dependency-configurations.html

Please update the library's build.gradle to apply this change.
