Simple DSD modulator for DSC2

Just to be clear, the FPGA firmware from the OP of this PCM2DSD thread is not open source (and that's the version I use). However, @MarcelvdG has shared some VHDL code for the FPGA board of this thread which implements his version of a sigma-delta PWM modulator, along with a few special extra features. In addition it may be helpful to know up front that programming an FPGA is very different from programming a computer. There is a whole new learning curve involved.

Also my open source reclocker project is a simple hardware reclocker, not a FIFO buffer too.
