Add support for formatting a disk with a hybrid MBR & GPT partition scheme. In this scheme, the primary partitioning method is GPT, but a valid MBR header is also written than can point to a subset of the GPT partitions on the disk (any partitions marked with the `--mbr` flag will be included in this MBR). The primary purpose of this method is to allow for SoCs that can only find a bootloader in an MBR partition to use GPT once the bootloader is running. As an example, older versions of the Raspberry Pi firmware can only parse MBR partitions to find a kernel (or other bootloader like u-boot), but once those have booted GPT partitions can be used. In addition to the partitions annotated with the `--mbr`, a "protective" GPT partition of type 0xEE is added, as the existence of such a partition is the indication to tooling that this a hybrid MBR and that the GPT partition table should be parsed instead.
