en el metodo readblocks se encuentra un error cuando se intenta hacer el reshape del arreglo junk, este error se produce porque no hay bytes suficientes para un bloque de datos. Para esto se propuso el nuevo metodo waitDataBlock que recalcula el numero de byte necesarios para un bloque y espera un tiempo (sleep) en caso no esten disponibles, se hacen tres intentos, si no se tiene exito el programa retorna 0.
