Set column width to the maximum allowed value

[sponomarev]

Maximum column width limit in MS Excel is 255 characters https://support.microsoft.com/en-us/office/excel-specifications-and-limits-1672b34d-7043-467e-8e27-269d656771c3

If this value is exceeded, MS Excel gets stuck and doesn't allow column resizing.

That looks great! This repo isn‘t actively maintained at the moment though, but I’d love to merge this into the community continued version at https://github.com/caxlsx/caxlsx – could you open a PR over there?
