Highlight

Multiple densification strategies are now supported in gsplat, including

• DefaultStrategy(): The original 3DGS densification process.
• DefaultStrategy(absgrad=True): Densification process from "AbsGS: Recovering Fine Details for 3D Gaussian Splatting"
• MCMCStrategy(). Densification process from "3D Gaussian Splatting as Markov Chain Monte Carlo"
