Sparse Mixture of Experts (MoE) VRAM & Bandwidth Sizer

Calculates memory footprint and memory-bandwidth scaling for sparse Mixture of Experts (MoE) LLMs across H100/H200 SXM5 clusters.

Formula: VRAM_weights = Total_Params * Precision; Active_Bytes = Active_Params * Precision; Bandwidth_Req = Active_Bytes * Target_TPS
