Constant rsmpeg::ffi::AV_FRAME_CROP_UNALIGNED

pub const AV_FRAME_CROP_UNALIGNED: u32 = 1; // 0x0000_0001u32

Apply the maximum possible cropping, even if it requires setting the AVFrame.data[] entries to unaligned pointers. Passing unaligned data to FFmpeg API is generally not allowed, and causes undefined behavior (such as crashes). You can pass unaligned data only to FFmpeg APIs that are explicitly documented to accept it. Use this flag only if you absolutely know what you are doing.
