Git clone takes ages because of big files in the history

Thanks for the suggestion of --depth=1! I'm going to add that shortly.

updater-script should pull the modems/radios and firmware update binaries. What each (cmnlib64.mbn, cmnlib.mbn) specifically does, I couldn't tell you as my knowledge of the Android filesystem is limited.

This portion was taken from the OxygenOS .zip - this part is updating the system portion of Android, so removing them would either not update the device or potentially cause booting errors. I run this script on my daily device, so I don't have a means to test removing them. :)

You can confirm such is not malicious as the package_extract_file function is triggering files originally copied from the .zip you specified from Oneplus (they don't actually exist anywhere in this repo).

Example:

# Extract ROM
echo "Extracting from the source image..."
unzip -q "$OXYGEN_PATH" firmware-update/* -d "tmp/"
unzip -jq "$OXYGEN_PATH" RADIO/* -d "tmp/firmware-update/"

• $OXYGEN_PATH is what you entered during the start of ./extract being run
• firmware-update/ is a directory pulled during the unzip command and destined for a temporary folder tmp/

If you unzip your OxygenOS zip, you'll see firmware-update as one of the main folders, with all of these files.

If you'd like to see it in action, add exit before the end of the script/any cleanup, or comment out the cleanup() function and you'll be able to see these folders before they get erased.

With regards to update-binary: this wiki should help
