This is to reduce the amount of required dependencies by not strictly requiring aria2c out of the box. You can always change the downloader back to aria2c in the config.
The browser to imitate can be set in the config:
For example,
```yaml
curl_impersonate:
browser: chrome110
```
It will default to using chrome110 if no value is set in the config.
A list of available Browsers are listed here: https://github.com/yifeikong/curl_cffi#sessions
The default is still SubRip SRT, but you can now change the output format to almost any of the available Codec options. There is no option to leave the subtitle format as-is yet. I.e., if there's a SRT and WebVTT subtitle, leave them both as-is.
Like always, you can configure a default in your config file, e.g.,
```yaml
dl:
sub_format: vtt
```
Note though that SSA, SSAv4, fTTML, and fVTT are not yet supported. There are no plans to support fTTML or fVTT.
