Create a TWRP-compatible device tree only from a recovery.img

With this script I tried to write TwrpBuilder script in Bash, and somehow I succeded, supporing more features

• Create device tree initial structure (like Android.mk, AndroidProduct.mk etc.)
• Android 10 support (beta)
• Add proper license headers in every file
• Automatically detect device architecture
• Pick stock recovery image info (eg. image size, kernel pagesize etc.)
• Inherit more infos directly from the device with ADB (optional)
• Create ad-hoc recovery.fstab
• Add needed init.rc files
• Take cmdline automatically
• System-as-root support
• dt.img support (not appended DTBs)
• dtbo.img support (device tree blobs overlay)
• Samsung Odin TAR support
• Samsung SEAndroid support
• Ramdisk compression support (LZMA, 7Z, GZIP etc...)
• MTK support
• Extract stock kernel automatically
• Fill BoardConfig.mk without needing to inherit external makefiles (like TwrpBuilder does), making a standalone device tree
• Easily improveable with a text editor, w/o needing to know any programming language
• Create a ready-to-push git repo in device tree folder

• A/B support

• SebaUbuntu - for this script
• EngMoPro - for archiving it
• Shubhamvis98 - for arm64 AIK
