   Packfile version is now 10 and the descriptor is still 0x51890ACE.
   // header for the packfile itself
   struct v_packfile_file_data {
   et_uint32 descriptor; // packfile descriptor used to validate data
   et_uint32 version; // version number of packfile
   et_uint32 header_checksum; // checksum of the header(after this field)
   et_uint32 file_size; // physical size (in bytes) of the source vpp file

   et_uint32 flags; // packfile flags
   et_uint32 num_files; // number of files in *data section
   et_uint32 dir_size; // number of bytes in directory section
   et_uint32 filename_size; // number of bytes in filename section

   et_uint32 data_size; // number of uncompressed bytes in data files
   et_uint32 compressed_data_size; // number of compressed bytes in *data section
   };
   struct v_packfile_entry_file_data {
   char *filename;
   et_uint32 start; // offset from start of v_packfile::data (if data is valid)
   et_uint32 size; // file size
   et_uint32 compressed_size; // compressed file size
   et_uint16 flags; // flags for this file
   et_uint16 alignment; // alignment requirement of this file
   };
   Flag data:
   // packfile flags
   #define PFF_COMPRESSED (1<<0) // packfile data is compressed
   #define PFF_CONDENSED (1<<1) // packfile data is run together
   // NOTE: the data of multiple files is recieved in a single read

   // Packfile entry flags
   #define PFEF_COMPRESSED (1<<0) // this file is compressed
