[pbs-devel] [PATCH v3 pxar 3/6] format: add helper type ContentRange

[Christian Ebner]

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
perform additional consistency checks on these entries.
