how to modifications so that it creates multiple out.json files

[lidongxue]

Setting resetOnNavigation does work but because puppeteer-to-istanbul creates unique filenames for the source files, the generated reports show many instances of the same files instead of a combined coverage which is the most common use case.

My workaround is that I vendored in puppeteer-to-istanbul and made modifications so that it creates multiple out.json files and I removed the unique filename feature. That did the trick for me.
