void ArchiveFile_Zip::AdjustOffset ( ) const

inlineprivate

fix up m_ofs (adjust it to point to cdata instead of the LFH).

note: we cannot use CDFH filename and extra field lengths to skip past LFH since that may not mirror CDFH (has happened).

this is called at file-open time instead of while mounting to reduce seeks: since reading the file will typically follow, the block cache entirely absorbs the IO cost.
