RFNoC Split Stream Block

This RFNoC block takes in a single CHDR stream and duplicates it, creating 'Number of Branches' (num_branches) output streams for each input stream.

The 'Number of Inputs' (num_inputs) parameter corresponds to the number of inputs that you want to split. That is, the block creates num_inputs instances of 1:num_branches splitters. The figure below illustrates how the CHDR ports are ordered when num_inputs = 2 and num_branches = 3.

              ┌──────────┐
 Stream A --->│0        0│---> Stream A
 Stream B --->│1        1│---> Stream B
              │         2│---> Stream A
              │         3│---> Stream B
              │         4│---> Stream A
              │         5│---> Stream B
              └──────────┘

Note that the number of available inputs and outputs are generated during FPGA build time, and GRC doesn't have access to how many inputs and outputs a particular target has. If the provided number for num_inputs or num_branches exceeds what is on the target, then a runtime error will be generated.
