IVGCVSW-2607 Implement Input range override mechanism
* Added the OverrideInputRange method to the Quantizer API
* Created OverrideInputRangeVisitor to implement the override mechanism
* Moved the quantizer utility functions to the new NetworkQuantizerUtils files
* Moved the map of quantization ranges out of the StaticRangeVisitor
and into the NetworkQuantizer
* Added unit tests
* Code refactoring and cleanup
