(Refactor) Move enums from Order.java to separate files and delete Order.java

[sweep-nightly[bot]]

Purpose

Currently, several enums are defined within the Order.java file. To improve code organization and maintainability, we move these enums to their own respective files.

Description

1. Create separate .java files for each enum:
   • CancelReason.java
   • ExecuteSide.java
   • RejectReason.java
   • Side.java
   • TimeInForce.java
   • Type.java
2. Move each enum to its respective file.
3. Update import statements in all affected files.
4. Ensure all unit tests pass after the refactoring.

Summary

• Moved the following enums from Order.java to separate files:
  • CancelReason
  • ExecuteSide
  • RejectReason
  • Side
  • TimeInForce
  • Type
• Deleted the Order.java file
• Updated import statements in the following files:
  • OrderBook.java
  • PriceLevel.java
  • OrderBookListener.java
  • OrderListener.java
  • Example.java
