[ENHANCEMENT] Add Support for LightUp in Puzzle Creator

[Chase-Grajeda]

Describe the current behavior of what you're trying to improve. If your enhancement request related to a problem, please also describe the problem.

Currently, we only have puzzle creation support for Nurikabe and TreeTent

Describe the improvement you'd like

We would like to introduce puzzle creation support for LightUp. Since this has already been done twice, there should be a fair amount of reference code to assist.

The non-placeable elements should be:

• Black square
• Black square with number
• Yellow square (lit space)
• Gray square (unlit space)

The placeable elements should be:

• Lightbulb
• Dot (asserts no lightbulb can be in space)

Note, the dots should be able to overlap yellow spaces

Describe alternatives you've considered

No response

Additional Context

See the Nurikabe editor and TreeTent editor for examples
