greatroar 63bed34608 restic: Clean up restic.IDs type
IDs.Less can be rewritten as

	string(list[i][:]) < string(list[j][:])

Note that this does not copy the ID's.

The Uniq method was no longer used.

The String method has been reimplemented without first copying into a
separate slice of a custom type.
