Add a visitor that adds PDA nodes to programs

[lorisleiva]

Whilst we can already create PDA nodes linked to accounts using the updateAccountsVisitor, the addPdasVisitor allows us to add "ghost" PDA nodes to programs (i.e. not linked to any account).

kinobi.update(
  addPdasVisitor({
    myProgram: [
      pdaNode('metadata', [
        constantPdaSeedNodeFromString('metadata'),
        programIdPdaSeedNode(),
        variablePdaSeedNode('mint', publicKeyTypeNode()),
      ]),
    ]
  })
);
