When an image file contains an alias of the camera model, rather than the official camera model, there is no way to relate back to the official model.

For example, with a T3i, I would expect to get back the official model of Canon EOS 600D (from data/cameras/canon/600d.toml) when calling camera.model. However, instead I get back the localized model Canon EOS REBEL T3i.

This can introduce difficulties when you want to branch behaviour based on the camera model as each localized case must be handled, rather than a single official model case.

Proposal would be to modify RawImage.{model, clean_model} to return the official model name, and add two new properties RawImage.{localized_model, clean_localized_model} that return the localized model name.
