🥰 [FEATURE] Support rotation for IconImageLayer

### 💻 Features description

Different roation for each icon image in IconImageLayer.

### 🏞 What problem does this feature solve

Could add direction info on icons.

### 🧐 What does the proposed API look like
```json
"source": {
"data": [
{"x": 1, "y": 1, "angle": 30},
{"x": 2, "y": 2, "angle": 90}
]
}
```

### 🚑 Any additional [like screenshots]

Start by locating the IconImageLayer implementation and the code that reads its source data. Use the proposed x, y, and angle values as the expected input, then verify that icons render with their individual rotations and that existing IconImageLayer behavior remains intact.
