Add guards against failures for missing input .mm files

Summary by CodeRabbit

• Bug Fixes
  • Enhanced error handling in georeferencing command-line tools. The tools now validate that map files load successfully before processing any georeference data. If a map file is invalid or corrupted, the tools fail gracefully with a clear error message instead of silently continuing with potentially corrupted data, which prevents downstream issues.

📝 Walkthrough

Walkthrough

Two CLI applications now validate .mm map file loading by checking the return value of mm.load_from_file(). If loading fails, a formatted exception is thrown, preventing subsequent operations on invalid maps. Previously, these failures were silently ignored.

Changes

Cohort / File(s)	Summary
Map Loading Validation mola_georeferencing/apps/mola-sm-georeferencing-cli.cpp, mola_georeferencing/apps/mola-trajectory-georef-cli.cpp	Added return value checks for mm.load_from_file() with formatted exception throwing on failure, replacing silent continuation with invalid map data.
