feat(WIP): Support for Balancer V3 hooks

[johngrantuk]

Adds support for Balancer V3 pools with hooks.

• The aim would be to add any Balancer approved/vetted hooks on a case by case basis.
• Config file is used to keep track of supported hook type and address
• Each hook must implement its own state and event handling (e.g. see src/dex/balancer-v3/hooks/directionalFeeHook.ts)
• Added a new event subscriber that will be used to track hook state
• Relevant hook state is used for pool maths and maths repo handles hook logic/calculation if required
• Sepolia directionalFeeHook is an example used for testing/integration to demo what is required
