[minor] renamed function to match filename
Minor formatting edits to spect_power_init_xblock
DSP scope now enumerates the input ports (instead of using cram/uncram)
Updated dsp_scope block in the library to reflect the changes
new blocks from the mux buffer test
xBlocks for FromWorkspace, ToWorkspace (for testbenches)
helper functions for low-level DSP48E implementations
used new DSP48E helper subblocks to clean up the diagram
4-input FFT tested, works with very specific parameter settings
on the latencies, so still plenty of work to do
fft_direct draws again
