Despite introduction of #1295, Electrons sometimes still end up corrupting their DCD data (mainly keys).


This PR introduces a bugfix for a scenario where a valid secondary sector (marked with SEAL_INVALID_V2) is treated as invalid if primary is lost, causing DCD erasure.

This PR also introduces a couple of footer validations and fixes an issue during v1 -> v2 format upgrade, where the footer is not getting properly initialized, as well as fixes EC public key extraction/write procedure.

I will merge into develop, but I also feel perhaps that we should merge into 0.7.0 also.
