Add card rotation to output file

Since we are able to rotate the cards to the right orientation we should also be able to store the rotation in the output file.

- [ ] Store the rotation in the card reader.
- [ ] Add the rotation to the result class.
- [ ] Add the rotation to the output file (*CardTitles.txt* in the folder *Image Data*).

Trace how card rotation is handled in the card reader and how the result class is populated. Then inspect the output path for CardTitles.txt in the Image Data folder and verify that the stored rotation appears alongside each card result. Done means rotation is preserved from reading through the result and output file.
