I thought I made something so you could contribute the extensions via code ... let me check!

Here it is in the extension point documentation:

Dynamically generate a list of supported file formats. Used to communicate the capabilieis of an external library such as GDAL, ImageIO-Ext or GeoTools.

class - FormatProvider instance used to list file format extensions and translated file format names. Should only be used to sort out "optional" file formats where supporting the format is sorted out at runtime. For static listing of a file format please use the normal fileService element.

(This was created specifically for ImageIO + GDAL combo so I wonder why it is not hooked up?)

In any case your pull request looks good - thanks!
