Demo command for SOT and MOT

[theoh-io]

Hello, thanks for your work on Tracking Unification which is really promising! I've seen that you are currently working on a demo script, but could you provide simple example commands for SOT and MOT inference ?

Some explanations of the arguments would also be appreciated, I'm not sure to understand the purpose of the experiment description file.

Thanks for your time,
Would be glad to help, working on the documentation for example.
