How to get the total zip size ?

[thiishfuoqdsjnfk]

Is your feature request related to a problem? Please describe.

I don't find any methods to get the zip file size
There is an internal zip_offset where data can precede the zip but how do we know the zip size when data is after the zip ?

Describe the solution you'd like
An accessible field like end_offset where the use can then

reader.seek(end_offset) to access the rest of the data

Maybe expose CentralDirectoryEndInfo ?

Thanks
