License

[virtualritz]

I understand libheif (the base for the libheif-sys and thus this crate) is under LGPL.

I think a warning should be placed in the README about this. If a user links such a dependencies statically into their binary, they will violate the license.

And that may happen involuntareily as a user currently need to go three levels down the dependency tree, to find out (like I did). 😁
