Perlin noise panics

[ctron]

Using a "too big" number (like the current milliseconds since the unix epoch) with the Perlin noise generator make it panic:

panicked at 'attempt to add with overflow', /rustc/9d1b2106e23b1abd32fce1f17267604a5102f57a/library/core/src/ops/arith.rs:108:1

I think that it is ok for the generator to fail (with a Result). But it should not panic.

Do you have a minimum example for this? I'm using the Perlin noise from this crate in a project so I'd like to have a look into it
