Dasel V3 early adopters

[TomWright]

I've been working in the background on a new version of dasel.

I've made what I would consider a lot of major improvements, and am almost at the point where I'd like to get some early adopters to run the latest version.

The idea for these early adopters would be:

1. Iron out any issues that I've missed.
2. Verify the syntax works and is as intuitive as I hope.
3. Gather suggestions/improvements that I can implement before it's released.

I'm currently working on the documentation over at https://daseldocs.tomwright.me/v3

Is anyone interested in helping me make this next major version as good as possible?
