Generate basic information about new protocol versions from BDS using Python and GNU objdump

protocol_info_generator_objdump uses GNU objdump to extract basic protocol information about a new version of Minecraft from Bedrock Dedicated Server, including the following:
- Current version (major.minor.patch)
- Whether or not this version is a beta
- Current protocol version
- List of packet IDs
The script currently patches the following files:
It will also generate stub classes for any new packets found.
No. It can only find some basic information like packet IDs and their associated names. Unfortunately, the compiled server doesn't retain any information about the names of struct fields, so the fields still have to be reverse-engineered manually.
In theory, yes. Since this tool essentially just requires a list of known packet names, their IDs, and some version info, it should be easily possible to alter the scripts to generate similar code for another project.
