[3.1.0] - 2024-12-04

Changes

• .h files from libheif was 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.

Fixes

• Deleted layout tests from bindings.rs (#8).
