Read comp_size and decomp_size for zip64

Browse Source 
As titled. For a zip64 archive file, `comp_size` and `decomp_size` are not stored in `p + MZ_ZIP_CDH_COMPRESSED_SIZE_OFS`, instead they are being stored in `pExtra_data`.

Here we need to read `uint64` for `comp_size` and `decomp_size`. Good that they are already of that type.
