Allow `cogen_dcf` to work on file names different from `bus.yaml`

[roncapat]

Is your feature request related to a problem? Please describe. I have a system which has two separate Canopen buses. I created bus_A.yaml and bus_B.yaml. I can't use dcf_gen because it uses hard-coded bus.yml.

Describe the solution you'd like The possibility to specify an alternative to bus.yml so I can call dcf_codegen twice in CMakeLists.txt

Generally it should work if you create folders for each bus in your config folder. Checkout canopen_tests package for this.
