[Feature Request] Add CLI option to not split or rotate images

[flying-sausages]

From what I gather, there is no way for me to have manga processed without horizontal images being either split or rotated. I have a kobo forma which has a gyroscope and can do 90deg rotation. It would be optimal to leave horizntal images as they are, and then I can actually rotate my device to fit the content if I so desire, or zoom into it manually.

The logic for the splitting image is pretty convoluted, and seeing as I have little python experience I would really need a hand with getting that done.

split and rotate configs are done here https://github.com/ciromattia/kcc/blob/4ec4c9966c727d6dac44507d34607bd7d2c5ed5c/kindlecomicconverter/image.py#L120-L146

comment this line should work https://github.com/ciromattia/kcc/blob/4ec4c9966c727d6dac44507d34607bd7d2c5ed5c/kindlecomicconverter/image.py#L109
