v2.6.0
- Checks current slot when parsing a Price account and set status to unknown if price is stale. Being stale means it is not updated in MAX_SLOT_DIFFERENCE slots (currently 25).
- Adds status field in PriceData to access the current status (considering price getting stale) easier.
- Converts Some type/status structs to enums to be able to use them in a cleaner way. It's backward compatible.
