Delete files within a channel

[keyursuchdeo]

Thanks @diessica for developing this utility. We've been struggling with file space issue on slack for quite a while, and this has come handy. I feel need to enhance this utility to support deleting within a channel.

• Accept channel name as input. Channel name can be left blank to delete files within all channels.
• Get channel id for the channel name.
• Delete files found within channel.
• Error if channel id is not found.

Let me know your thoughts. I can send you a PR.

I'm glad it helped!

It'd be great to have this feature.
