tape/helpers/snapshot_reader: sort chunks by inode (per index)
...
sort the chunks we want to backup to tape by inode, to gain some
speed on spinning disks. this is done per index, not globally.
costs a bit memory, but not too much, about 16 bytes per chunk which
would mean ~4MiB for a 1TiB index with 4MiB chunks.

tape/drive: improve tape device locking behaviour
...
by implementing a custom error type that is either 'TimeOut' or
'Other'.
In the api, check in the worker loop for exactly 'TimeOut' errors and continue only
then. All other errors lead to a aborted task.

it seems we do not need it, since the EXTDECC flag is only used for
determining if the drive is capable to be configured via
ADI (Automation/Drive Interface) which we do not use at all.

Some changer seem to append more data than we expect, but correctly

For each descriptor entry, read as much as the size given in the
subheader (or until the end of the reader), else our position in
the reader is wrong for the next entry, and we will parse
incorrect data.
