I mapped with hector slam. Using odometry with it, I was able to create this map:

This is pretty close to the original. I don't have the ground truth image, so I cannot make any comparison locally, but, trusting my eyes, it seems to be a pretty good one. Playing with parameters in a launch file, you can probably improve it. Here is the launch file I used to create the above:
