Add a verbose option

A few things that come to mind

1. Show commands spawned by ncu
2. Show HTTP request response, in particular responses that could not be parsed as JSON (e.g. when Jenkins authorization fails, it returns XML)
3. Pipe stdout and stderr, also do not use spinners if verbosity is on in case the output is overwritten

首先追踪 ncu 的命令生成、HTTP 响应处理，以及 stdout/stderr 或 spinner 输出路径。添加一个 verbose 选项，涵盖生成的命令、无法解析的 HTTP 响应，以及不带 spinner 的流式输出。启用详细模式后，能够看到每项所请求的细节，即表示完成。
