increase sql table owner_public_key from varchar(256) to 512

[mallochine]

The MIRACL public key format has 258 characters (example: 0420ec9dd58f2d16babe5eddd0990472ef7f05fd707e3a4171e61ba9360fe4a3891d9bcf8a86b0b270d104c1a2a093f744d27793927910b38be9883ec0b06ca3490569516d05cfdfb66f64ac13681905ec639930dc66ae889944d4a0e3fbf249fc0d52adb860e55487251acbd90e8f1b5563e71e67af1e110ce986ff41df34a7ed)

very sadly, this 258 string is just 2 character more than the 256 limit.

The error message I'm seeing is:

{"code":"invalid_parameters","error":"invalid_parameters: Invalid allocation id passed.verify_allocation: verifying allocation transaction error: ERROR: value too long for type character varying(256) (SQLSTATE 22001)"}

It can be replicated with this curl call (although the six network is currently down unfortunately)
