"""酷我搜索（对应 sdk/kw/musicSearch.ts）。

||
|

搜索接口 `search.kuwo.cn/r.s` 返回的是带单引号的 JS 对象字面量，必须走
|
||
`util.obj_str2json` 而不能直接 json.loads。音质清单在 `N_MINFO` 字段里，
|
||
`;` 分隔多档、每档形如 `level:ff,bitrate:2000,format:flac,size:32.43Mb`；
|
||
`mflac`/`mgg`/`mmp4`/`zp` 等加密码流的 bitrate 是 20000+ 的随机值，不在
|
||
4000/2000/320/128 四档之内，天然被过滤掉。
