series: Add test for slice length way bigger than series length (#2093)

The need for such a case arises from languages with bounded integer
types like Rust where the specific edge case (slice length equals series
length plus one) can be solved by unstable solutions that would overflow
for any greater slice length input.

For instance, in Rust, with no type casting, computing `digits.len() + 1
- len` will panic for `len > 6`.
