The sizes of offsets in the `.debug_str_offsets.dwo` section depend on the format of compilation or type units referencing them: 4 bytes for DWARF32 units and 8 bytes for DWARF64 ones. The fix uses parsed units to determine the actual size of offsets in the corresponding part of the `.debug_str_offsets.dwo` section.
