Add Hyperbolic GCN layer

1

Adds the HGCN layer from [Hyperbolic Graph Convolutional Neural Networks](https://arxiv.org/abs/1910.12933) to partially address #1334. This operator offers increased expressiveness over hierarchical graph topologies, e.g. tree structures. Adapted to PyG from...

This PR adds support for symmetric quantization when compressing/decompressing tensors. This is useful for comparing the performance of both symmetric and asymmetric quantization. - supports storing compressed tensors without zero...

Where can we download the ground-truth `.bin` files for running the tests? This would be helpful for further development:) Thanks!
