- Add reedsolo library for RS error correction (32 symbols = 16 byte correction per 223-byte chunk)
- Protect entire payload (header + data) with RS encoding
- Store 3 copies of length header with majority voting for robustness
- Handle RS chunking overhead (varies based on data size)
- Update capacity calculation to account for RS overhead (24 bytes prefix + variable RS overhead)
- Add RS to dct, web, and api optional dependencies
- Update about.html with v4.1.0 Reed-Solomon feature
- Update module docstring
This fixes DCT decode failures with certain carrier images that have
uniform areas causing unstable DCT coefficients.
