Unit lengths option

[dantreble]

Awesome utility, thank you!

I was a bit confused about distances originally, my test model is huge and vertex weights are capped at 1.0. I worked out what was happening by looking at the uvs after using the uv writer.

For my purposes I made the max length 1.0 by adding:

d /= np.max(d)

In compute distance here https://github.com/lukas-toenne/geodoodle/blob/main/geometry_math.py#L98

It would be amazing if that were an option exposed in the ui.

Thanks again!
