To do this mount all ESP partitions and check all the binaries there to see if they match any entries in the new dbx. If we applied the update when a hash matched, we would unintentially 'brick' the users machine, as the grub and shim binaries *have* to be updated first. This functionality does reimplement the PE hashing functionality found in sbsigntools and pesign. This was done for 4 main reasons: * There were some memory safety issues found when fuzzing random binaries * Executing the tools hundreds of times was a lot of overhead * Operating from a blob of immutable mmap'd memory is much faster * We only need a very small amount of functionality from both tools
