Filter non-provable `BlockSampledDataLake` request

[rkdud007]

Context

Some of the header fields might return None ( e.g. in case calling non-supported eip fields for later block ), or return some non properly handled data ( e.g ExtraData field returns "0x" in some situations ), and there might potentially more of those cases.

As HDP rust repository should filter out non-provable data before sharing to Cairo Program, it is important to identify the potential issues and return proper error message for non-provable cases.
