libgyoto8 binary package in Ubuntu Focal riscv64

 Gyoto aims at providing a framework for computing orbits and
 ray-traced images in General relativity. It consists in a shared
 library (this package), utility programs (in the gyoto package), and
 a plug-in for the Python 3 and Yorick programming languages (in
 python3-gyoto and yorick-gyoto respectively). Gyoto can be extended
 with plug-ins (see libgyoto8-dev).
 .
 The standard plugin (stdplug) is included in this package. A plug-in
 for extending Gyoto in the Python 3 language is shipped in the
 python3-gyoto packages.
 .
 MPI parallelization requires the gyoto-bin and mpi-default-bin packages.
