Update test scripts for adjacent class

[Uio96]

• [x] The current test script uses the image of six shapes, which are not adjacent. Need to simulate a new image with adjacent pieces.
• [x] Also the testAdj function in the board needs to be updated.

Remember to note that adjacency is based on a threshold. That means it is possible to have an image of separated objects get treated as adjacent by having a slightly higher threshold for adjacency.

It also shouldn't be too hard to make a puzzle with just nine squares that have different colors and are close to each other but not touching. Makes it easy to calibrate and then to solve.

Yep, I understand. I just thought the previous visualization was not that good so I created a new one for the adjacent case.
