The spec mentions that this tag is present in all TLV files, so its
absence means the file is invalid and should trigger an error.

Ah right, `Tlv` keeps a reference to the `Firmware` instance, which
would become a local variable if we used a helper. We could work around
this by using more generics, but that cascades into other ownership
issues and is more trouble than is worth for now.
