Add front/rear images for Nokia devices

[jbemmel]

All images are 226x19 PNG, and can be imported using the enhanced tool (separate PR)

Hey @jbemmel, rather than keeping the images in the same folder as the definitions lets create a new folder for all images.

I already have an implementation ready. I will get that merged to master soon so you can utilize it

@jbemmel I have added documentation regarding the front and rear images. All device images must be placed within the manufacturer folder within the elevation-images folder in this repo. The manufacturers folder needs to be named exactly the same as the device-types and the module-types folders.

After the manufacturer folder is created, you can then start adding your images. It is required that the file name follows this format:

1. The first part of the name must be a part of the slug which identifies the device, i.e. 7220-IXR-H3
2. The second part of the file name indicates whether it is a front or rear image, with a dot as the delimiter. This should look like .front or .rear
3. The final part of the file name is the file type. This can be any of the following types ('bmp', 'gif', 'pjp', 'jpg', 'pjpeg', 'jpeg', 'jfif', 'png', 'tif', 'tiff', 'webp'). Of course you need a dot in front of the file type as well, i.e. .png or .jpg, etc.

Please let me know if you need anything else.

Hey @jbemmel is this still needed/still being worked on?
