This fixes the following issues (flagged by cppcheck):
[libi2pd/ECIESX25519AEADRatchetSession.cpp:537]: (error) Buffer is accessed out of bounds: m_NSREncodedKey
[libi2pd/Identity.cpp:22]: (error) Buffer is accessed out of bounds: keys.publicKey
[libi2pd/Identity.cpp:22]: (error) Buffer is accessed out of bounds: publicKey
[libi2pd/NetDb.cpp:70] -> [libi2pd/NetDb.cpp:69]: (error) Iterator 'it' used after element has been erased
[libi2pd/SSUData.cpp:186] -> [libi2pd/SSUData.cpp:187]: (warning) Shifting 32-bit value by 63 bits is undefined behaviour.
