Unable to read content in Cell Comment

[AaronBui-gif]

Hi,
I used the instance method Roo::Excelx.comment(row, col, sheet = nil) to read the comment of a specific cell and it only read the Author name of the comment without the content. I found a solution as link below: https://github.com/roo-rb/roo/pull/562/files and it successfully works as expected. Can you guys update the master asap. Thank you
