Sort out Howling Fist and Enlightment usage at range

[LTS-FFXIV]

This pull request includes several changes to the MNK_Default class in the BasicRotations/Melee directory, focusing on the usage of the Howling Fist and Enlightenment abilities. Additionally, there is an update to the ECommons subproject commit reference.

Key changes:

Ability Usage Adjustments:

• Modified the HowlingSingle property to include Enlightenment alongside Howling Fist for ranged attacks against single target enemies and set its default value to true (BasicRotations/Melee/MNK_Default.cs).
• Simplified the AttackAbility method by removing the conditional check for the number of hostiles and ensuring Enlightenment and Howling Fist are used regardless of the number of enemies (BasicRotations/Melee/MNK_Default.cs).
• Updated the AttackAbility method to use Enlightenment and Howling Fist with the skipAoeCheck parameter based on the HowlingSingle property (BasicRotations/Melee/MNK_Default.cs).

General Cleanup:

• Removed redundant checks and usage of Enlightenment and Howling Fist in the GeneralGCD method (BasicRotations/Melee/MNK_Default.cs).

Subproject Update:

• Updated the ECommons subproject commit reference to a new commit (ECommons).
