Need to update the spec of verify_poc_details/3 with this new error.

Did it slightly differently though and made the error return a tuple of tuples.

Problem
When ledger POC verification fails we can't really tell whether it failed due to incorrect challenger or the block hash.
Solution
This switches the return type for
poc_v3:verifyto be anok | {error, ...}and passes it down.
