Doesn't build with libheif 1.19+

[felixonmars]

There appears to be some API changes: strukturag/libheif@ecdeb8f#diff-3d7d4ade3135524be963ec0b461e86d0b1fbfef0c1083a1f2230811a92ac9a17R77

At the moment I haven't finished a version of libheif-rs with support for libheif 1.19.
However, if you are using Linux on x86_64 architecture, you can use the current version of libheif-rs with libheif 1.19 if you disable the default features of the crate in your Cargo.toml.:

[dependencies]
libheif-rs = { version = "1.0.2", default-features = false }

When libheif 1.19 becomes available in Microsoft's vcpkg, I will add support for it.

Thanks. I have verified that this fixes it on x86_64. But unfortunately I'm trying to build it on riscv64 :(

I have released libheif-sys 2.2.0 with the following changes:

• .h files from libheif were embedded in the crate sources.

• Changed build.rs to use embedded .h files for the bindgen build stage
  instead of .h files from the installed libheif library.

  Now you can link the crate with any version of libheif
  that is backward compatible with the version supported by the crate.

So you can remove the changes I suggested earlier and try to do a cargo update to use this new version of libheif-sys.
