Add Kdenlive adapter

[vpinon]

Hello,
Here is a proposal to be able to inter-operate with the libre video editor Kdenlive.
I've run some successful tests on my side, and our community is waiting for such feature for long.
Please guide me if I have to do something more.
Many thanks for OpenTimelineIO!
BR,
Vincent

This is cool! Will it support straight mlt files as well?

[vpinon]

Hum, I was not aware of hard formatting rules enforcing, I will update it.
It will not eat any MLT file, it is expecting Kdenlive structure (which may match Shotcut too, but not checked)

[vpinon]

I'm so sorry I should have read the contribution guide /o
Now make test & make lint pass correctly with python3.7

Let us know if/when you're ready to land this PR.

[vpinon]

It would be fine if merged as it is today.
We can always improve it later (e.g. effects & transitions handling) but nothing foreseen soon.
Many thanks!
