Add function to read/write cell background color

[sp00ktober]

Hello :)

Maybe i just did not find it but it seems there is no way to actually get the background color of a specific cell. It would be really nice to have this ability.

But beside that its a really nice lib to work with xlsx files, super easy to use! Thanks for the work.

Hi @sp00ktober,

I'm glad you like it :)

Unfortunately, cell formatting is not possible at the moment. The primary goal of OpenXLSX has been data access, i.e. reading and writing of cell data, and not so much formatting (e.g. cell color, merged cells, fonts, etc.). It is on my todo list, but no promises on when it will be done.

I see, and i understand that. Then i‘ll just wait for it, im not in a rush :)
