Pull request overview

This PR enhances the comparison view to display the actual year when Street View imagery was captured, rather than just a boolean availability status. The change replaces Bool with a new StreetViewAvailability enum that captures both availability status and the capture year.

Key changes:

• Introduced StreetViewAvailability enum with .available(year: Int) and .unavailable cases
• Updated Google Street View Metadata API response parsing to extract the year from the date field
• Modified comparison view to display the Street View capture year when available, falling back to the current year in camera mode

The date parsing doesn't validate that the parsed year is reasonable for Google Street View imagery. According to the Google Street View Metadata API documentation, the date field contains imagery capture dates which typically range from 2007 onwards (when Street View was launched).

The current implementation would accept dates like "0001-01-01" or "9999-12-31" without any validation. Consider adding a sanity check to ensure the year falls within a reasonable range (e.g., between 2007 and current year + 1) to catch potentially malformed API responses or data corruption issues early.
