Fix: Pass through version in init=True case

[chillenzer]

Thanks for this great project! I've just started using it and it works quite well!

However, this tiny oversight had me scratching my head for quite a while: In init=True mode, the version parameter of ROCrate.__init__ is not passed through to __init_from_tree.

Hi @chillenzer, please add a unit test to cover this case

Hi, thanks for the quick response! Sorry, if it's not best quality, just hacked it together in the browser. While looking through the tests, I've only found CLI tests. (Might have overlooked something. If so: Please point me there!) I've added a CLI test and then realized that probably the reason for this not having popped up earlier is that the CLI doesn't support this. So, I've taken the liberty to add a CLI option for this as well. You should feel warmly invited to suggest a better name (naming is hard!) or scold me for this frivolous act. I've explicitly not chosen --version as convention has it reserved for printing the software version.

Yes, I should've definitely not just hacked it in the browser. I'll do it properly next week.

Sorry for the delay. @simleo should work now.
