SlabRarity.sol
The SlabRarity contract simply denotes an enum that is used across the protocol.
[INFO] Caution for future releases
Future protocol developments and protocol releases should bare in mind that the numerical enum value for each respective SlabRarity are linear against when they are defined. This means that external platforms (e.g. the subgraph) will reference the numeric value as opposed to the string so the original state should be maintained and extended, rather than replaced.
