Feature request: additional fields to extract from the podcast episode

[swehba]

It would be really nice to also extract and have placeholders for the following:

• {{Station}} — the name of the podcast station/show vs. the episode {{Title}}
• {{EpisodeNumber}} — if episodes are numbered for the given station
• {{RunTime}} — the duration of the episode (e.g., 1:23:45)
• {{Tags}} — any tags associated with the episode
• {{AiredDate}} — when the episode aired

I don't know if any of this is possible, but thought I would ask.
