Improve error message for failed reference lookups

Summary

We currently generate an error message containing the complete parameters object for failed reference lookups, cf.

Lines 717 to 719 in edd6767

    
           let mut v = self 
        
               .interpolate(root, &mut state) 
        
               .map_err(|e| anyhow!("While resolving references in {self}: {e}"))?;

While this is manageable when using small test inventories, this generates a massive error message for real-world Project Syn inventories.

Python reclass uses the following error type for failed reference lookups: https://github.com/kapicorp/reclass/blob/856b34cb77811d665c6346883238d436ac5c4924/reclass/errors.py#L202-L210

Acceptance criteria

Adjust the reference lookup error message to be more concise
Release reclass-rs

Implementation ideas

Try to mimic the Python reclass error message
If necessary, track additional state during reference resolution

	let mut v = self
	.interpolate(root, &mut state)
	.map_err(\|e\| anyhow!("While resolving references in {self}: {e}"))?;
