CLI has no support for sign language

[kristophm]

Hi there! I'm trying to create a film with a sign language video track (which is formatted as an audio track wav file as per ISDCF specification), using the CLI. However, when looking at the code, it seems like there is not an audio channel mapping for sign language.

Reference: https://github.com/cth103/dcpomatic/blo ... li.cc#L232

Would it be possible to add this?

I would submit a PR to add this in, like
```c
} else if (channel == "SLV") {
return dcp::Channel::SIGN_LANGUAGE;
```
but I don't have enough knowledge of the code base yet, sorry!

Please let me know if I can be helpful in another way.

Thanks so much Carl! I'm assuming it will be available in the next release? Appreciate the quick response and all the development you've done on this!

Right, yes in the next release. Hopefully within a week or so.
