This is a smaller version of #1416, but for 32-bit tag numbers.
The PR is intentionally small and only changes handling of
Tag
andTagNumber
types.The use case for 32-bit tag numbers instead of 16-bit is the Image4 format used in apple firmware files which needs PRIVATE tags with 32-bit numbers.
Breaking changes from the original PR:
u32
nowu8
forTag
andTagNumber
do not make sense anymore, this also applies toTag::octet()
Length::for_tlv()
just assumed, that a tag is always one byte, it now somehow needs to know about the specific tag we are looking at
