Change license from MIT to GPLv3

[shuxiao9058]

As this project use large chunk code from https://github.com/karthink/gptel and discussed at https://github.com/karthink/gptel/issues/91, I prefer change the license from MIT to GPLv3.

This issue is primarily for discussing this decision.

For more information on GPLv3 please read: https://www.gnu.org/licenses/quick-guide-gplv3.html
