`Osmosdr_Signal_Source` implementation of a `SignalSource`.
- The `Osmosdr_Signal_Source` implementation learned a new parameter `if_bw` to
manually set the bandwidth of the bandpass filter on the radio frontend.
- The `UHD_Signal_Source` learned two new optional parameters
`device_recv_frame_size` and `device_num_recv_frames` for overriding
[transport layer defaults](https://files.ettus.com/manual/page_transport.html).
- The new configuration parameter `Channels_XX.RF_channel_ID` allows to specify
the signal source per channel group.
- Allowed the CMake project to be a sub-project.
