Add FIR Filters

Adds the highPass and lowPass FIR Filters
ADC/DAC Sample Rate to 50kHz

Sets the delay within the clocking block to set the ADC/DAC at a 50kHz
sample rate.
Instantiate highPass filter

Instantiates the highPass filter
Instantiate highPass filter

Instantiates the highPass filter
sinkValid update

Updates sinkValid so that it is high while no new data is being read,
and low while new data is being input to the ADC
highPassOutput to DAC

sends highPassOutput to DAC
Add pixelOutput to directory

Adds the pixelOutput file to the project directory
Instantiate pixelOutput

Instantiates pixelOutput and updates the file:
1. Changes input of characterPixels to input of highPassOutput and
lowPassOutput.
2. Removes all logic for setting pixel values.
3. Removes the ifReached reg which was only used in testing.
Add syncPulses to directory

Adds the syncPulses file to the directory
Instantiate syncPulses

Instantiates syncPulses. Removes hData & vData from syncPulses because
they were unnecessary and not being used. Removes clk3hz and that logic
because it is not necessary.
