[Feature] Configure Spinner component

[Coteh]

What is the problem?
Spinner component currently just has the center circle (the sun) and the three green circles around it (earth, venus, and mercury). It would be nice if this could be customized for different use cases (e.g. for auth loading page, for other pages, etc.)

Your solution
Allow for customization of:

• Number of planets
• Speed of each planet
• Color of planets
• Potentially shape of planets too...?
