Merge method

Implement method to merge incoming bytes to the main frame
byte description:
```bash
{
      "x": 81,
      "y": 59,
      "color": "#000000"
   
 }
```
Bytes should overlap previos bytes. Then the final image should be stored in the db
storage format:
```bash
[{
      "x": 81,
      "y": 59,
      "color": "#000000"
   
 },
{
      "x": 81,
      "y": 59,
      "color": "#000000"
   
 }]
```
