[Debian-astro-maintainers] Bug#956694: spdlog refers to files that it does not ship

[Ole Streicher]

Control: retitle -1 spdlog refers to header files that it does not ship
Control: reassign -1 spdlog-dev 1.5.0
Control: affects -1 src:sopt

This is an internal inconsistency of spdlog, therefore I am re-assigning
it. For me, the workaround in #953855 didn't work either, since then I
just get a number of unresolved fmt symbols:
