Fixes issue 11

- Use [cholespy](https://github.com/rgl-epfl/cholespy) for the Cholesky solver, making the dependencies lighter and easier to install
- Added an optimization to the rendering code

:warning: These changes have an influence on the performance of different blocks of the experiments pipeline, so you may notice some timing discrepancies when running the experiments.

This repository contains the implementation of our research paper "Large Steps in Inverse Rendering of Geometry". It contains the parameterization code as a python package, as well as code to reproduce several figures from the paper.
