Add OLED-1.3Inch-128O64D-7Pin Footprint

• Add: OLED-1.3Inch-128O64D-7Pin footprint.
• Please refer to the 7-Pin 1.3-Inch OLED Display Module for the physical schematic diagram and size description.
• The packaging diagram is as follows:
• Regarding some of these issues:

1. On the purchase page, the information provided by the merchant points to a supplier named "中景园电子" company, but I cannot find the data manual for this module on the supplier's official website.
2. I am unable to find the corresponding 3D model for this module.
3. The size chart provided on the merchant page was manually measured. After drawing according to this size, I found that the hole positions could not be aligned. Therefore, I personally measured the submitted packaging size. This size has been verified through 1:1 printing to ensure that the hole positions correspond.
4. The following are dimension diagrams and actual measurement images:

Note: The actual measured size of the outer border is slightly larger than that of the footprint. This is because when dividing the physical production, the border is not completely at right angles and has a slight V-shaped shape, which leads to a slightly larger measured size.
