ZipArchive.RemoveEntry slow when removing in bulk

Nice library, thanks.

I've found that ZipArchive.RemoveEntry is slow when removing many entries (e.g. 1,000 in an archive of 60,000). It starts off ok but slows down to 1 file per second fairly quickly.

Could this be an issue of re-building between each removal, similar to #485
?

thanks

Probably. Did you use the method in your code?

Not in anything final - just currently experimenting with the library as it has nice support for multiple formats.
