React-calendar: DefaultDetail as a new prop

[oliverdendis]

Thanks for great calendar component 👍

I really like the props maxDetail and minDetail. Sometimes, I really miss something like defaultDetail, in some cases like date of birth it is much better for users (we have tested it on UX tests) to set default detail to year, because user firstly chooses year then month and after that day, which can be annoying when user has days as default detail.

There are some solutions available which allow that feature (e.g air-datepicker) but only in jQuery. Generally, there is lack of react datepickers with it and it can be a really useful enhancement.

I would like to create a PR for that, what do you think about it @wojtekmaj ?

I think it's an excellent idea! I'll transfer this issue to React-Calendar as it's React-Calendar which handles date picking on a calendar UI :)

Investigated; we already have this, but it's called view and not defaultView. Just checked; definitely works :) Try e.g. view="decade".
