This function tries to open a Microsoft Excel (xls/xlsx) file or, an wbWorkbook with the proper application, in a portable manner.
On Windows it uses base::shell.exec() (Windows only function) to
determine the appropriate program.
On Mac, (c) it uses system default handlers, given the file type.
On Linux, it searches (via which) for available xls/xlsx reader
applications (unless options('openxlsx2.excelApp') is set to the app bin
path), and if it finds anything, sets options('openxlsx2.excelApp') to the
program chosen by the user via a menu (if many are present, otherwise it
will set the only available). Currently searched for apps are
Libreoffice/Openoffice (soffice bin), Gnumeric (gnumeric), Calligra
Sheets (calligrasheets) and ONLYOFFICE (onlyoffice-desktopeditors).
