[Feature] Adding D-FINE-seg for Instance Segmentation

[ArgoHA]

📄 Description

Hi, thanks for the work and open Geti platform.
I am an author of D-FINE-seg repo and paper. I think it might be useful to extend Geti's instance segmentation models with D-FINE-seg. I have implemented training, exporting (including OpenVINO and int8 accuracy aware quantization), inference for both object detection and instance segmentation tasks.

Attaching benchmarks I ran on Intel N150 iGPU (latency comparison):

Model	Format	F1-score	Latency (ms)
D-FINE-seg S	FP32	0.264	431.2
D-FINE-seg S	FP16	0.264	272.2
D-FINE-seg S	INT8	0.243	205.0
D-FINE S	FP32	0.272	188.4
D-FINE S	FP16	0.271	120.8
D-FINE S	INT8	0.250	76.3

🎯 Objective

Implement a better instance segmentation model to Geti
