about the implement of RLE on two-stage 3D HPE mehtods

[ChenyangWang95]

Hi,
I'm interested in RLE. it is a nice job.
I notice that you embed RLE into two-stage 3D HPE methods, such as SRnet, but I didn't see it in this repo. can you introduce the implementation detail about this? Is there any else that needs to notice?

Thanks very much!
