- enh: be more verbose when tip position cannot be computed
- setup: bump afmformats from 0.7.0 to 0.10.0

- setup: bump afmformats from 0.6.0 to 0.7.0 (metadata fixes)

- feat: IndentationGroup.get_enum returns a curve from an enum value
- setup: bump afmformats from 0.5.0 to 0.6.0 (hdf5 export, improved tab
export)

- enh: set parameter `baseline` to "vary" for all models
- fix: make sure that `model_key` is set before `params_initial`
when fitting with kwargs (otherwise, `params_initial` might reset)

- feat: add function `Indentation.get_rating_parameters`
- feat: compute additional ancillary parameter "Maximum indentation"
- feat: new functions `model.get_parm_unit` and updated
`model.get_parm_name` to work with ancillary parameters as well

- feat: allow to define ancillary parameters for models and use them
during fitting by default
- feat: `Indentation.get_initial_fit_parameters` now automatically
computes common and model-related ancillary parameters if no
initial parameters are present
- enh: allow to set the `model_key` in more functions of `Indentation`
- ref: use `idnt` to represent Indentation instances
- fix: preprocessing steps not stored in `Indentation.preprocessing`
- setup: bump afmformats from 0.4.1 to 0.5.0
