Image size based on columns and rows instead of pixels

[leo-arch]

Would it be possible to implement an option to set the size of an image as columns x rows instead of width and height in pixels?

For example, instead of the current:

img2sixel -w PIXELS -h PIXELS ...

something like this (mimicking the -s option in chafa):

img2sixel -z COLUMNSxROWS ...

See #154.

Thanks for pointing this out @t-bltg. Do you need me to recreate this issue in libsixel/libsixel?

It would probably have more chances of getting fixed, yes.
