Upgrade image-size to atleast 0.6.2

With the current version of image-size, the xlsx-template package won't work on Electron.

Related issue fixing the issue on Electron: image-size/image-size#39

So image-size should atleast be upgraded to 0.6.2 (I tried with yarn resolution and it works fine with 0.6.3)

Same, it also causes the output file from Webpack or NCC to not working.

This problem was fixed by upgrading the image-size to 0.4.0.

Apologize to all for extremely long delay. I did update to image-size 1.0.2 in version 1.4.3. Let me known if you have any issues.
