This change adds three new methods to the DataType class that help with element-based stride calculations and alignment checks: 1. element_stride(): Returns stride in elements instead of bytes 2. is_stride_element_aligned(): Tests if stride is aligned with element boundaries 3. is_stride_aligned(nbytes): Tests if stride is a multiple of given bytes Fixes issue #1207 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>

int return is consistent with other c api functions that provide boolean answers
