Extract boot.img or init_boot.img from Delta (maybe) payload

[Rt39]

I'm a OnePlus user and I want to extract a full OTA, I've got the same problem as #4 saying its delta payload. I only want to exact the init_boot.img file for rooting, so even if the python version cannot exact all the files, it works fine for me, but this program won't exact anything. I'm here to ask if this program could add the feature of extracting part of the imgs even it cannot exact all.

Here is the information about the OTA:

FILE_HASH=lB3Bowg24rmpf1MwJA3FAaYOUGl3Q8GssIKhum2zWzo=
FILE_SIZE=7631160751
METADATA_HASH=2wiZUXE/5xURtFkUxB+F+Kz10Fway7EPBTNnT1uieqQ=
METADATA_SIZE=290530

oplus_rom_version=V13.1.0
security_patch=2023-10-05
security_patch_vendor=2023-10-05
