Export Aseprite to Mosi (Lua Simple Script Test)

UPDATE: +AMosExport2.lua script with more properties
OffsetX, OffsetY - variables to Offset*Size pixels

Just a test Lua Script for Export Sprites to Mosi from Aseprite.

MOSI by Zenzoa - https://zenzoa.itch.io/mosi

I made Lua Script. For Aseprite to export sprites for Mosi.
I'm not good with Lua and Aseprite. And I never upload anything to itch_io...
My first time... ^_^'
Anybody can freely update/change my script to make more advanced version.

PS 
1) In first version we should to draw only by ff000000 (black color)
2) In Version 2 we have to draw in white color.

PPS It's a very bad code, if you ask me ^_^'''
Still not sure how to make it more advanced.
