Command to allow the user to buy more effects (#424)

# Description

- Create a command to generate an embed for the user to be able to buy more effects
- This embed will contain the details about the effect as well as 2 buttons; Confirm and Cancel
- The confirm button will call the button event to:
    - Remove the currency from the user
    - Give the user the effect to their inventory
- The cancel button will just disable the buttons, so the user can't accidentally use it if they don't want to.
