ValueConv implementations for exif-oxide
ValueConv functions perform mathematical conversions on raw tag values to produce logical values. Unlike PrintConv which formats for display, ValueConv maintains precision for further calculations and round-trip operations.
All implementations are direct translations from ExifTool source code.
