IPTV-EPG provider no longer works in v1.1.0.6

[paul-chambers]

telly release with the issue:
telly, version 1.1.0.6 (branch: dev, revision: dafac1f)
build user: root@c8b3d5116b6b
build date: 20190509-14:43:23
go version: go1.12.5

Last working telly release (if known):
unknown

Operating environment (Docker/Windows/Linux/QNAP, etc.):
Linux: Ubuntu 18.04 inside a KVM virtual machine

Description of problem:

The 'IPTV-EPG' provider no longer works. This appears to be because IPTV-EPG is now using Cloudflare, and Telly isn't providing a 'host' header when making the HTTP request, so Cloudflare doesn't know which HTTP host the request is for.

If I use the 'Custom' provider, and provide the M3U and EPG URLs explicitly, Telly does start successfully.

and then crickets...

Additional information:

[chazlarson]

This will probably be addressed by removing the IPTV-EPG custom provider since there's no particular advantage to using it over the custom provider, which does work.

[chazlarson]

named providers will be removed from the next release; they don't add any value at this point.
