Enhancement: Removed loguru

[ibraheem-opentensor]

• Removed loguru from the repo
• Defined custom 'events' in the logger

Edit: We have added first_party_loggers which will enable this logger not to get removed as third-party. Once we release this change, we can move forward and depreciate loguru

@ibraheem-opentensor let me know if this is ready to review + merge

@gus-opentensor This change is dependent on our upcoming release which adds first_party_loggers. Once we roll that out, we can mark this ready to go.
