- introduce reset_ak function to reset the /tmp/anykernel directory to allow for multi-partition mods; use after changing the AK2 shell (block, etc.) variables again
- make patch_cmdline more intuitive; match the string, and if it doesn't exist add the replacement string, and if so replace with it
- allow AVBv1 signing of recovery by adding simple partition type detection based on name
- restore LD_LIBRARY_PATH after AVBv1 signing to be friendly to recovery when flashed in between other zips
