Electron Demo "Click here to select a file" does not load file properly.

When clicking on the button highlighted in red, the file prompt shows but the UI does not respond to the selected file.

The functionality highlighted in green works properly.

Tested with the example xlsx files here.

This is related to an API change somewhere between 1.7.5 and 9.

https://github.com/SheetJS/sheetjs/blob/master/demos/electron/index.js#L68 the code uses electron.dialog.showOpenDialog and grabs the result.

The current version returns a promise https://www.electronjs.org/docs/api/dialog#dialogshowopendialogbrowserwindow-options

However 1.7.5 returned an array of strings https://github.com/electron/electron/blob/v1.7.5/docs/api/dialog.md

The easiest thing might be to change the call to showOpenDialogSync, adding a proper guard for the case that the dialog is canceled.
