### hex
使用16进制编辑器编辑二进制文件。
**用法：**
```bash
hex <filename>
```
**示例：**
```bash
hex test.bin
hex kernel.sys
```
**控制键：**
- `↑ ↓ ← →` - 移动光标
- `Page Up / Page Down` - 滚动视图
- `0-9, A-F` - 编辑字节值
- `S` - 保存文件
- `Q` - 退出编辑器
**说明：**
- 显示文件的16进制字节值和对应的ASCII字符
- 每行显示16个字节，分为8个字节一组
- 显示每行的偏移地址（8位16进制）
- 光标位置用白色背景高亮显示
- 文件修改后显示 [MODIFIED] 标记
- 支持查看和编辑任意大小的二进制文件
- 按 S 键保存修改到文件
- 按 Q 键退出编辑器（不保存修改）
**界面示例：**
```
