Fix GH-1725
<itunes:explicit> accepts "explicit", "yes", "true", "clean", "no" and
"false" as valid values.
Here is the <itunes:explicit>'s description in
https://help.apple.com/itc/podcasts_connect/#/itcb54353390:
> The <itunes:explicit> tag indicates whether your podcast contains
> explicit material. You can specify the following values:
>
> * Yes | Explicit | True. If you specify yes, explicit, or true,
> indicating the presence of explicit content, the iTunes Store
> displays an Explicit parental advisory graphic for your podcast.
>
> * Clean | No | False. If you specify clean, no, or false, indicating
> that none of your podcast episodes contain explicit language or
> adult content, the iTunes Store displays a Clean parental
> advisory graphic for your podcast.
I don't know whether <itunes:explicit> value is case sensitive or
insensitive. But the current implementation is case insensitive.

When you change this to true, you may need to add more tests.
