"""猫耳FM 广播剧集列表（对应 sdk/me/album.ts，web 通道，匿名免签）。

接口: https://www.missevan.com/dramaapi/getdramaepisodes?drama_id=&season=&page=&order=0&pageSize=
结果在 info.episodes.episode[]（name/sound_id/pay_type/vip）；剧名在 info.drama.name。
注意：getdrama（不带 type=2 时）的 info.episodes.episode 同样可用（MusicFree 插件用法），
本接口支持翻页故用之。
