Consider moving to ttrv

Hey @ajak, thx for taking care of rtv after the original author dropped support. However, I feel that there has been little development going on here since. In the meantime a 2nd fork https://github.com/tildeclub/ttrv emerged, which seems more active.

As two projects are unneeded, would it be a possibility to close this project and move to ttrv to combine efforts? Thx for considering!
