Question: istanbul version

Hello,

I'm currently using v8-to-istanbul to convert chromium headless coverage output via puppeteer to a format that can be consumed by https://github.com/SitePen/remap-istanbul.

Thanks for your work btw!

If the output of this package is in the "old" istanbul format as linked in the README:
https://github.com/gotwarlost/istanbul/blob/master/coverage.json.md
why is it part of the new istanbuljs repository?

Furthermore I cannot find further information on the new istanbuljs/nyc format: is there some documentation and where can i find it?

Are there any plans to support the new nyc format in this package? (well, i don't know of the differences between the formats, just that i cannot easily merge them)
I would like to switch completely to nyc.

Could you please shed some light on these questions.
Thanks!
