Error on cmd 'npm run export'

Found one error which is easy to correct. On my machine we run 'npm run export' and get the error of 'rleRow.split('#') is not a function'. This line of code is found in the decoder script. The error happens because rleRow is an array and not a string. By renaming rleRow to rleRowArray, and copying the characters of this array into a new string by name of 'rleRow' the output will then be correct since rleRow is now a string and now it has the string.split() function.

I made my edit inside the FOR loop of the function decode(). My FOR loop looks like this:

let rects = []
for (let row = 0; row < rleRows.length; row++) {
const /RENAMED to rleRowArray/ rleRowArray = rleRows[row] // ex : #ffffff32#0000004#ffffff28

	//TEMP FIX
	var rleRow = '';

	if(rleRowArray instanceof Array)
	{
			for(var x = 0; x < rleRowArray.length; x++)
			{
				rleRow += rleRowArray[x];
			}
	}

	//END TEMP FIX

	const rectsPerRow = generateRects(row, rleRow)
	rects.push(rectsPerRow)
}

Now, rleRow is a string and will work as expected.
