Fix for wrong parameter "templateImage" + allow for changing both font face and font size independently (#8)

* Fix for wrong parameter "templateImage"

The param « imageTemplate » should actually be « templateImage ».

I haven’t replaced the variables names because that’s not important,
even though they are backwards too.

* You can change the font and font size independently

We were not able to change the font size OR the font face, it had to be
both which is incorrect
