Exiv2

I am just creating lens correction profile for the above lens and the same time I would like to correct its recognition in the exiv2 too.
The below modification was successfully tested with the the Tamron lens but not tested with the affected Canon EF 300mm one.

If you agree, please introduce the below modification:
