Add LIRA-8 based on Camomile

This one is quite heavy on the CPU. It might only work on the Duo X.

I've talked to the author and he would look at making a fully Heavy/HVCC compatible version, that should be able to use a lot less CPU (since there is no libpd involved), but it requires pulling out all the GUI-tricks and replacing some other non-compatible pd-objects.

Also your PR just copies the amd64 binary from the repository, which obviously will not work for any MOD units.
