describe the feature you'd like to see

A custom filename format feature would be useful for e.g. those that like to have a consistent naming scheme when archiving videos or audio. For example, if cobalt were to support an arbitrary JavaScript snippet, one could specify the following template:

`[${service.toUpperCase()}] ${name} (${id})`

...where the variables are defined as follows:

service = "YouTube"
name = "Rick Astley - Never Gonna Give You Up (Official Music Video)"
id = "dQw4w9WgXcQ"

...cobalt would download the file as [YOUTUBE] Rick Astley - Never Gonna Give You Up (Official Music Video) (dQw4w9WgXcQ).mp4. As audio and video files have different parameters, the user would be able to specify a different template for videos and audio.

As I have not contributed to cobalt, I'm not sure if eval would be a security risk (I don't know if the filename is determined client-side or server-side). If it is, a simple token replacement would also be great, e.g. [$service] $name ($id), where cobalt would simply do:

filenameTemplate
  .replaceAll("$service", serviceName)
  .replaceAll("$name", mediaName)
  .replaceAll("$id", mediaId);
