read_directory(archive) -> files dict (new reference)
Given a path to a Zip archive, build a dict, mapping file names
(local to the archive, using SEP as a separator) to toc entries.
A toc_entry is a tuple:
(__file__, # value to use for __file__, available for all files,
# encoded to the filesystem encoding
compress, # compression kind; 0 for uncompressed
data_size, # size of compressed data on disk
file_size, # size of decompressed data
file_offset, # offset of file header from start of archive
time, # mod time of file (in dos format)
date, # mod data of file (in dos format)
crc, # crc checksum of the data
)
Directories can be recognized by the trailing SEP in the name,
data_size and file_offset are 0.
