Is your feature request related to a problem? Please describe.
软件非常漂亮优雅，现在软件确实能听播客，但没有音频控制界面，无法调节进度或调节倍速（这俩可以说是播客刚需）。而且也无法记住进度（每次点播放都会从头播）
This is an beautiful and elegant app, and can play podcast, but can't control play speed and go back or forward, also this app can't remember where this podcast is played.

Describe the solution you'd like
提供音频控制界面，可以调节进度和倍速，并且默认记住播放位置
Provides an audio control interface that can adjust progress and speed, and remembers the playback position by default

Describe alternatives you've considered
调用系统已经安装的播放器（比如mpv、PotPlayer）通过URI播放网络音频
Call the player installed on the system (such as mpv, PotPlayer) to play network audio through URI
