Hardcoded threshold in save_preds

[LoaferCH]

There is a hardcoded threshold value of 0.3 in save method.

innofw/innofw/core/datamodules/lightning_datamodules/segmentation_hdf5_dm.py

Lines 104 to 105 in f0bfa99

	pred[pred < 0.3] = 0
	pred[pred > 0] = 255

Also it may be unnecessary since thresholding is already done in forward method, so the output already is in unit8 type.

innofw/innofw/core/models/torch/lightning_modules/segmentation.py

Line 67 in f0bfa99

outs = (logits > self.threshold).to(torch.uint8)

So, only this line may be left:

innofw/innofw/core/datamodules/lightning_datamodules/segmentation_hdf5_dm.py

Line 105 in f0bfa99

pred[pred > 0] = 255
