/**
 * The legacy U-Boot image format (uImage), as created by `mkimage`: a 64-byte
 * header followed by the image data (e.g. a Linux kernel, a ramdisk or a
 * script). The header describes the data (OS, CPU architecture, image type,
 * compression, load and entry point addresses, name) and protects both the
 * header and the data with CRC-32 checksums.
 * 
 * U-Boot's newer FIT (Flattened Image Tree) format is not covered by this spec.
 * @see <a href="https://github.com/u-boot/u-boot/blob/ece349ade2973e220f524ce59e59711cc919263f/include/image.h">Git tag "v2026.07"</a>

/**
 * Whether this type stores ASUS firmware information (`asus_info`)
 * rather than an image name (`name`).
 * 
 * The header doesn't say which one it is, so we infer it using a
 * heuristic based on the layout of the `asus_firmware_information` type.
 * If ASUS firmware info is present, the first byte (the major kernel
 * version number) is a small integer (i.e. not a printable character),
 * and byte 4 (first byte of the product ID/model name) is a printable
 * character. An empty name is not mistaken for ASUS information, because
 * its byte 4 is a null byte.
 * 
 * The highest known major kernel version number is 9 (e.g. in
 * `DSL-N55U_9.0.0.4_380_3925-gad8f412_Annex_A.trx` from
 * <https://dlcdnets.asus.com/pub/ASUS/wireless/DSL-N55U/FW_DSL_N55U_90043803925.zip>,
 * released on 2016-08-04 and listed on
 * <https://www.asus.com/supportonly/dsl-n55u/helpdesk_bios/>). ASUS
 * seems to use such high major versions (9, sometimes 7) for beta
 * releases, whereas regular releases use 3 (or 1 in older firmware).
 * 
 * It can also be 0, in particular due to a bug in the MediaTek MT798X
 * build of ASUS's `mkimage` (it reads the `-V` values from fixed `argv`
 * positions, even though it parses the options using `getopt()` - see
 * <https://github.com/blocktrron/tuf-ax4200-gpl/blob/a4fe37f4d78473f97c6d47cf93d97c3811af90cc/release/src-mtk-MT798X/Uboot-upstream/tools/mkimage.c#L317-L333>).
 * For example, this is the case in
 * `RT-AX52_3.0.0.4_388_34015-g9488655.trx` from
 * <https://dlcdnets.asus.com/pub/ASUS/wireless/RT-AX52/FW_RT-AX52_300438834015.zip>,
