Added Knowles_SPH0645LM4H.

3D model merge request: kicad-packages3D!876 (merged)
Rule violations explanation:
- Violating EC02: Pads 1, 2, 4, 5, 6 are square, because that's how they are in the datasheet.
- Violating F6.3: Pad 3 is missing a paste layer, because I had to drew the solder paste shape manually, using several polygons, as is shown in the datasheet.
