[AIV]: Bugs with the aiv to aivjson logic

[gynt]

Hi gynt, i took a closer look at the positions (why i used x-99...): Only the default values are flipped for the function "to_json".
Currently: "invert_x=True, invert_y=False"
To work with the SC DE: "invert_x=False, invert_y=True".
Interestingly, the function "from_json" works fine with "invert_x=True, invert_y=False". However I noticed that the units were missing, when i opened the created .aiv file.
