Move license away from GPLv3 and strong copyleft

[Ganwtrs]

Is your feature request related to a problem? Please describe.
GPLv3 hinders devices with an immutable root of trust. GrapheneOS is planning on overhauling or replacing AOSP apps like AOSP Calculator, but they wouldn't be able to include OpenCalc because it uses the GPLv3.

Describe the solution you'd like
A license that is not strong copyleft, preferably a permissive license.

Describe alternatives you've considered
Weaker copyleft like the GPLv2 would cause less trouble but it can still be an issue
