Quickly build a tilemap from a tileset and a CSV file.
Create a CSV file with the cells mapping to tile numbers. (0 represents the top-left tile of the tileset)
Then load the tileset image and CSV file into the program. Specify how many pixels wide each tile is and click generate.
To build the program, open tilesetWidget.pro in Qt Creator (Qt 5.15.2), run qmake, and build.
