Add "transfer from Day One" support#86

Currently Day One entries can be exported as .json zipped package but it is not readable by Stoic app.

Hello everyone, thanks for commenting on this post and being so patient!

I am happy to announce that Day One import is live for everyone for a few weeks now. Go ahead and test it, and let us know if you had any issues while doing so.

Open this link on your phone to import your data from Day One to stoic:

Happy journaling!

I as excited to test this, but I keep getting:

No valid DayOne entries found in any JSON files

The main journal I’m trying to migrate is ~1 GB zipped, and I can import it into other apps that offer Day One import, e.g. tested the same file successfully with Everlog.

Any hints?
