[pbs-devel] [PATCH v2 pxar 2/5] format: add helper type ContentRange

[Christian Ebner <c.ebner@proxmox.com>]

The new `ContentRange` type will be used to store content ranges to
be used when accessing a pxar archive via the decoder, but with
additional payload reference information in order to be able to
perfom additional consistency checks on these entires.
