crystract 1.0.1 (2026-05-28)

Refactored internal CIF extraction logic to robustly check for multiple alternative CIF tags when parsing chemical formulas, structure types, and space group names/numbers.
Updated README installation instructions to include options for both stable (CRAN) and development (GitHub) releases.
Improved the package vignette by updating Wyckoff filtering examples (from 4a to 4d) and adding a new section demonstrating how experimental errors are extracted from CIF loops and propagated through calculations.
