Potential copyright violation in RawDeflate libraries #134
Description
Hi,
While I was reviewing the source of this library I looked into RawDeflate.inflate and noticed it's under a different licence than the rest of this ISC project.
The rawinflate.js file currently mostly retains the copyright of the original author, Masanao Izumo, which originally put this library under the GPL. The copy of rawinflate.js in this repository is very similar to that file except it shares similarities with a gplv2 version of this file by dankogai. Putting this together we likely have some gplv2 license code being used in this project which has viral and potentially incompatible elements (learn more here).
Do you know how this file ended up in this project? As well, do you think this is the only instance of differently-licensed third-party material in the project?
Thank you,
David
