Fixes

• Fixed license identifiers from LGPL-2.1 to LGPL-3.0
• Fixed C++ wrapper parameter names (mn/mx → min/max)
• Corrected randomRange documentation (min >= max → min > max)

Improvements

• Applied MISRA C:2012 formatting (unsigned suffixes on all integer literals)
• Improved trng.c file header description
• Added version and Arduino Library Manager badges to README
• Added author email in library.properties

• Uses rejection sampling to eliminate modulo bias in trng_randomRange.
