Introduced various shields.io badges to both Czech and English README files to display project maintenance status, license, stars, issues, pull requests, downloads, and code size. This improves project visibility and provides quick repository insights for users.
The README files no longer mention the need to downgrade to esp-idf version 5.4.1, reflecting that this workaround is no longer necessary. Updated both Czech and English documentation accordingly.
Refactored XT211Uart to handle cases where the lock is not initialized, preventing null dereference. Added fallback to base read_array for non-hardware UARTs in read_array_quick_, improving compatibility with BLE-backed UARTs.
