Pull Request Overview

This PR updates RcppArmadillo from version 14.6.2-1 to 14.6.3-1, upgrading the bundled Armadillo C++ library to version 14.6.3. The primary purpose is to fix OpenMP-related crashes in Cube::slice() on Arm64 CPUs by upgrading the minimum required OpenMP version from 3.1 to 4.0.

Key changes:

• Upgraded minimum OpenMP requirement from version 3.1 (201107) to 4.0 (201307)
• Added seq_cst memory order clause to atomic read/write operations for thread safety
• Updated version numbers and documentation across all relevant files
