progress does not work

[SebiTimeWaster]

following the "onUpdate" example in https://stuk.github.io/jszip/documentation/api_jszip/generate_async.html all log statements execute at the same time when the zipping is done, rendering the callback useless. (run in browser)

I noticed the same. By the time updateCallback runs, all files are already downloaded into browser, so this does not provide any functional progress indicator for actual downloading of the files.
