Handle long state variable declarations

[fvictorio]

contract Contract {                                                                                                             
   bytes32 private constant DOMAIN_SEPARATOR_TYPEHASH = 0x035aff83d86937d35b32e04f0ddc6ff469290eef2f1b692d8a815c89404d4749;      
 }

becomes

contract Contract {                                                                                                             
     bytes32 private constant DOMAIN_SEPARATOR_TYPEHASH =                                                                        
         0x035aff83d86937d35b32e04f0ddc6ff469290eef2f1b692d8a815c89404d4749;                                                     
 }

@mattiaerre can we remove the codecov integration? It's way more annoying than useful.
