feature request: <Ability to read any cell inside the worksheet>

Feature Request

Adds the ability to "check" if a specific cell contains a value of any kind. First time ever commenting and a lower skilled programmer. Forgive me if this is already in the works

The rust_xlsxwriter library can only write Excel files and not read them so there won't be any future syntax for reading cell data. Sorry.
