Provide a comparison with TMSU

[ngirard]

I think it would be very useful to provide a comparison with TMSU. It is similar in scope, written in Go, and in active development.

I understood from the Reddit thread that you weren't familiar with it, and IMHO it is an additional reason for this comparison. I'm pretty sure that it would be beneficial for you to get to know about TMSU's design choices and feature set.

Furthermore, TMSU's author (@oniony) started to program in Rust, so there could be an opportunity for you guys to join your forces and work together, which would be amazing.
