roc-copy tool copies samples from input to output, performing necessary conversions if necessary.
Currently roc-copy requires that both input and output should be files, and fails otherwise. It does it by checking has_clock() value, which is true for devices and false for files.
Solution
We can allow one of the input or output to be device (but not both, because roc-copy doesn't have clock drift compensation).

Testing
Ensure that "copying" from microphone to file, and from file to speakers works fine.
