Detailed Description

Helper class to deal with datapath configuration

From the user perspective, each channel datapath is configurable in the following modes
  - 'latency'
  - 'capture'
  - 'playonce'
  - 'playloop'
  - 'pattern'
  - 'zeroes'

On the other hand datapath for each channel is configured in terms of
  - buffer mode
  - data source
  - bx that triggers data-valid  high
  - number of valid words

  PathConfigurator translates the mode into the  buffer mode + data source and applies them to the block
