Rust bindings to libwebp, libwebpdemux, and workarounds for static/inline C functions and some other miscellaneous stuff.
Much of the API doc comments from the C header files have been included with their rust FFI counterparts.
Raw, unaltered symbols are under the raw module. Also most of the raw symbols are re-exported under the sys module, with more idiomatic rust naming conventions. E.g. the WebPValidateConfig function is renamed to webp_validate_config.
