Pull request overview

This PR adds a new standalone “PBI fixer” utility to clean up measure DAX by removing a leading 0+ / 0 + prefix, and re-exports it from the sempy_labs.semantic_model package.

Changes:

• Added fix_avoid_adding_zero() fixer that scans all measures in a semantic model and strips a leading 0+ prefix from measure expressions.
• Added a package re-export so callers can import fix_avoid_adding_zero directly from sempy_labs.semantic_model.
