When this flag is passed to cvd_internal_start/assemble_cvd, it uses information mined from the `AndroidBuild` hierarchy to create a new `super.img` file that is represented as composite disk with indirections to logical partitions stored in separate files. Part of the implementation of `liblp` was copied into this project, because the public API did not provide the functionality we needed in order to generate the proper super image header in isolation, without the logical partition contents. The implementation is similar to the composite GPT disk generator, which uses indirections to provide data for the GPT physical partitions. Bug: b/476228593
