/**
 * A bootloader image which only seems to have been used on a few ASUS
 * devices. The encoding is ASCII, because the `releasetools.py` script
 * is written using Python 2, where the default encoding is ASCII.
 * 
 * A test file can be found in the firmware files for the "fugu" device,
 * which can be downloaded from <https://developers.google.com/android/images>
 * \sa https://android.googlesource.com/device/asus/fugu/+/android-8.1.0_r5/releasetools.py Source
