zip_append does not replace when file already in archive #111
Description
Appending a file to a zip archive does not overwrite the old file if exists but adds a new file.
This results in archives with replicate file names :
> cat("lala",file="lala.txt")
> cat("lblb",file="lblb.txt")
> zip::zip("lala.zip","lala.txt")
> zip::zip_list("lala.zip")
