### Core & Engine
* `image` (default): Enable features required for image manipulation and reading.
* `image_formats` (default): Enabled by default. Compile all `image` crate image format support options.

* `encoders` (default): Enable barcode encoders.
* `decoders` (default): Enable barcode decoders.
* `multi_barcode_readers` (default): Enable support for reading multiple barcodes in a single image.
