Implement T.4 MH (Modified Huffman) encoder

- encoder/mh.rs: Full T.4 Group 3 MH encoding implementation
- Uses ITU-T T.4 standard Huffman tables for white/black runs
- Adds EOL codes and RTC (6 EOLs) at document end
- Class2Send now encodes pixels to MH before transmission
- CLI convert command shows MH encoded size

Test result: 467KB raw pixels → 14.6KB MH encoded (~32:1 compression)

Add Class 2 fax protocol support

- class2/commands.rs: EIA/TIA-592 Class 2 AT command definitions
- class2/send.rs: Class2Send implementation for simpler fax sending
- CLI: Add --class option for send command (1 or 2)
- CLI: Add --class2 flag for test command
- Tested with Conexant V90 modem - all Class 2 commands working
