[Bug Report] Hardcoded variables

[HelinXu]

Hi!

Thanks for open sourcing this amazing work!

I might be wrong, but I think several hardcoded variables should have been passed in through the config file. e.g. in the following example, the min_pts_num=50 should have been passed in via the cluster_npoint_thre: 50 in the config file.

DyCo3D/model/pointgroup/pointgroup.py

Lines 574 to 576 in 17d22c2

	proposal_idx, proposal_len, scores = self.generate_proposal(mask_logits.squeeze(dim=0).sigmoid(), object_idxs,
	threshold=0.5, seg_pred=semantic_preds_, inst_pred_seg_label=inst_pred_seg_label,
	min_pts_num=50)

This took me quite a moment, as small objects with fewer than 50 points were missing in the outputs, even if I turned cluster_npoint_thre in the config file to 5 : )
