Allow users to override the default TFTP port (69) when connecting
to servers running on non-standard ports. The port can be specified
via -p or --port flag.
Examples:
tftp -p 6969 get 192.168.1.1 config.txt
tftp --port 1069 put myserver firmware.bin
If a port is embedded in the host (host:port format), the --port
option takes precedence.

Add command-line programs for TFTP operations:
tftpd - TFTP server daemon:
- Configurable root directory for serving files
- Optional write support with --writable flag
- Optional file overwriting with --overwrite flag
- Custom port binding (default: 69)
- Path traversal protection for security
tftp - TFTP client:
- get command for downloading files
- put command for uploading files
- Support for both octet and netascii modes
- Verbose mode for debugging
Also adds comprehensive integration tests that verify client-server
communication with real network I/O.

This commit introduces a sans-IO TFTP protocol implementation following
RFC 1350. The protocol crate provides:
- Packet types: RRQ, WRQ, DATA, ACK, ERROR with full serialization/parsing
- Error codes as defined in RFC 1350 Appendix
- Transfer modes: octet (binary) and netascii
- Client and server state machines for managing protocol flow
- Comprehensive tests for all packet types and state transitions
The sans-IO design separates protocol logic from I/O operations, making
the code testable and reusable across different I/O implementations.
Key design decisions:
- Mail mode is explicitly rejected as obsolete per RFC 1350
- Block numbers wrap around at 65535 for large file support
- State machines emit events that tell the I/O layer what to do next
- All protocol-specific values are documented with RFC citations
