Add ability to rotate images - some timestreams are not in landscape

[TimeScience]

Orientation:
0 = no change (landscape)
-1 = Rotate image 90deg left
1 = Rotate image 90deg right

I'll add in the CSV column, but I'm not sure if i will get this implemented before the deadline.

Also we can just leave it blank for no change, this would make it
'' = no change(landscape)
'-1' = rotate image 90 degrees left
'1' = rotate image 90 degrees right
Do you want a value:
'2' = rotate image 180 degrees
