Purpose

This pull request implements several enum classes to represent various aspects of an order management system and adds corresponding unit tests to ensure their correctness.

This pull request was created to solve the following GitHub issue:

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

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

Handle all imports and references in the files.

Enums to be moved (this is not an exhaustive list, please check for any additional enums): Remove the enums from the original Order.java file and move them to their own files.

CancelReason ExecuteSide RejectReason Side TimeInForce Type

Move enums from Order.java to separate files

Description:

Refactor the Order.java file by moving the enum definitions to their own separate files. This will improve code organization and maintainability. Update all necessary imports and references in affected files.

Tasks:

Create new enum files in the src/main/java/com/coralblocks/coralme directory:
- CancelReason.java
- ExecuteSide.java
- RejectReason.java
- Side.java
- TimeInForce.java
- Type.java
- CancelRejectReason.java
- ReduceRejectReason.java
Move the corresponding enum definitions from Order.java to their respective new files
Update Order.java:
- Remove the enum definitions
- Add import statements for the newly created enum files
Update any other files that reference these enums:
- Add import statements for the new enum files
- Update any fully qualified enum references
Review and update any documentation that mentions these enums

Test:

Verify that all existing tests in src/test/java/com/coralblocks/coralme still pass after the refactoring
Add new unit tests for each enum in their respective test files (e.g., SideTest.java, TypeTest.java, etc.) to ensure they function correctly after the move

Description

This pull request introduces the following enum classes:

CancelReason: Represents reasons for order cancellation
CancelRejectReason: Represents reasons for rejecting a cancel request
ExecuteSide: Represents whether an order is a taker or maker
ReduceRejectReason: Represents reasons for rejecting an order reduction
RejectReason: Represents reasons for rejecting an order
Side: Represents the side of an order (buy or sell)
TimeInForce: Represents the time in force of an order
Type: Represents the type of an order (market or limit)

Each enum class implements the CharEnum interface and includes a CharMap for efficient lookup by character representation. The classes also include methods for converting between enum values and FIX protocol codes where applicable.

Additionally, this pull request adds comprehensive unit tests for each enum class to verify their functionality, including value retrieval, character representation, and FIX code conversion.

The Order class has been updated to use these new enum classes, improving type safety and readability.

Summary

Implemented new enum classes: CancelReason, CancelRejectReason, ExecuteSide, ReduceRejectReason, RejectReason, Side, TimeInForce, and Type
Added unit tests for all new enum classes
Updated Order class to use the new enum classes
Improved type safety and readability in the order management system
Enhanced compatibility with FIX protocol by adding FIX code conversion methods
