adjust Value.ignore() to make ignoring of other types than String ava…

…ilable

Sometimes we have a JDBC Row where 0 value means "null" but ignoring does only work with strings until now.
object.as(Row.class).getValue("value").ignore(BigDecimal.ZERO) should ignore a found 0 without calling
Value.of(object.as(Row.class).getValue().asString().ignore("0")
