Version 2.1.0 released!

Hey guys! I just released version 2.1.0 of Twisted IK 2, which adds constrained FABRIK in 2D as a modifier choice! Its taken quite a bit of work to get it working, and it's not perfect, but it does give decent results while still being performance friendly. Again, its not perfect, but it works decently in my testing and I'll likely continue to work and refine it over time. Here's a GIF showing it working in the Godot editor:

I have also released the code containing the constraints implementation under the MIT license, as there is little examples with constrained FABIRK and so I hope sharing how its done will help anyone looking to make their own constrained FABIRK in 2D in the future.

Additionally, this release also includes a change to 2D CCDIK: you can now choose to solve CCDIK forwards, backwards, or forwards and backwards, so you can get the result you are looking for. This makes CCDIK much more suited for many more limbs, as it now can give a more natural result (especially with forward and backwards solve mode). You can change the CCDIK solve mode in the inspector. I would recommend seeing if you can get decent constrained IK results with CCDIK over FABRIK, as currently CCDIK is a bit more stable in how it solves constraints.

Finally, I have also started to work on the 2D documentation for 2D IK. This release includes the first page for 2D IK documentation, which covers Skeleton2D setups and what IK solvers you may want to use depending on your 2D project use case.

That's all for this release! Next release will probably focus around adding 2D physics bone support. Thanks for reading and for your support!
