Allow Polorizer & Depolorizer Option Flags

[sarvalabs-manish]

• Allow Polorizer and Depolorizer to have option flags to change the encoding/decoding behaviour of the buffers.
• These flags must also be able to be passed through the Polorize and Depolorize functions
• Some of the possible flags can include
  • Performing Document Encoding (assists Fix Document Encoding for Nested Structures #28 )
  • Disabling Custom Encoding for types that implement the Polorizable and Depolorizable interface
  • Manipulating the buffer size limits (assists Enforce Message Size Limits #6 )
  • Encoding Behaviour for Big Numbers, Byte Slices and Byte Arrays
