Add Lua method to allow verbose channel data on User fired Events

[bundasmanu]

Description

Included a new lua method to allow verbose channel data in user fire events.
verbose-channel-events at this point only works for FS internal fired events, but could be useful to apply that in user fired events.

Usage example:

event:verboseChannelData() -- will try to use `Unique-ID` to get channel
event:verboseChannelData("call-uuid") -- will check Event header `call-uuid` to get the channel

• Without argument, will use Unique-ID to get channel and populate info;
  • If Unique-ID is not available, and no argument is provided, the event will not contain channel data;
• Passing argument, indicating the event header to be used to get the channel uuid;
  • If channel exist, verbose is applied;
