[Standardization] Standardized Return Codes

[TanmoySG]

Currently the Scripts/Handlers in AuthLib return a text-based response/prompt. Using such prompts have fundamental issues -

• If any text-based return statements aren't written correctly, they can break the system
• Any missing punctuation or whitespaces may also break the system if not parsed correctly

For these reasons a standardized Return Statements Guide with Return Codes and Statements can help in global, standardized and proper usage.

[Checkpoints]

• [x] Create a RETURN_STATEMENT_HELPER script
• [x] Add Script/Scope based Codes and statements
• [x] Use different code-fragments to mention/specify different scopes
• [x] Mention Associated Statements
• [x] Add Usage README

[Snippets]

Instead of using return statements like these

return "Incorrect OTP"
return "Correct OTP"

Return Codes can be used

class RETURN_CODES:
    # Sample Implementation
    self.x001 = "Incorrect OTP"
    self.x002 = "Correct OTP"

return RETURN_CODES().x001

[Additional Information]

Table with configurations for different codes can be added in the README.
