- The `UHD_Signal_Source` learned to dump data in folders that do not exist,
*e.g.*, if `SignalSource.dump=true`,
`SignalSource.dump_filename=./non-existing/data.dat`, and the `non-existing`
folder does not exist, it will be created if the running user has writing
permissions. This also works for absolute paths.
