Where is pyheif's copyright?

[augustolf]

I checked in the LICENSE but only found this:

Copyright [yyyy] [name of copyright owner]

[lupsin]

For wheels probably license was always GPL2.0, as we can see in wheels:
pyheif.libs/libx265-6b0a4f49.so.199,sha256=VVydIMPxuT0mV8Cq3ZCtZQfPWIIzzRKDScIktQZL-Hg,6407792
encoder that only available under GPL2.0.
So for whole project LICENSE is GPL2.0 when it used from PyPI. And license is Apache 2.0 when it is builded from source.
