tsMuxer CLI lacks features of tsMuxer GUI

Seems like this code for generating the META file should be included in the CLI, minus the enabling/disabling function (unless there is an elegant way to incorporate that.)

I'm new to the project but I will consider submitting a pull request if I have time to figure it out.

Thanks!

To be more precise - in order to automate usage of the CLI, it seems the code to generate the ".meta" compatible output should belong to the core tool, not UI code. Assuming a user wants to complete one step (input file -> output file with all tracks) there is no reason to complete a manual and intermediary step of writing a .meta file by hand.
