Add support for range float field

No way it’s not working out of the box in the latest module version, could you please check that?

I currently have it working with the following:
Drupal Core: 10.2.7
Single Content Sync: 1.4.8

When you say the latest version, do you mean 2.0.x branch?

Actually any field type should be automatically exported out of the box since 1.4.7

The simple field implementation will be removed since it's no longer needed. See 📌 Clean up SimpleFieldDeriver in favor to use GenericField Active
