Features: labels, no GRUB menu, different FSes, persistance.

livecd-tools is no longer functional (see livecd-tools/livecd-tools#253), so it is not possible to have some of its features from a first-party tool. Ideally, Media Writer would support many of the features from livecd-tools, including:

• User-configurable filesystem labels (like livecd-iso-to-disk's --label)
• User-configurable overlay/persistance (like --overlayfs,--overlay-size-mb)
• User-configurable filesystem formats (ext2/3/4, btrfs, etc.) (like --format)
• User-configurable partition sizes (like --format)
• User-configurable automatic grub menu bypass (like --nomenu)
