Fix toeplitz_coeffs_stride() for minimal sized poly (#18) 
Fix an edge case in FKMulti when the chunk length was the same as the polynomial size, resulting in writing outside the return array in `toeplitz_coeffs_stride()`.

Ben Edgington 9d1b622f21 Make zero poly work for large numbers of missing indices 
Previously, like the Go code, calculating the zero polynomial would fail
for very lare numbers of missing indices. For example, 253 missing with
a domain size of 256 - this is where the number of partials flips from 4
to 5 and more working space is needed.

With this commit, the zero polynomial can be calculated right up to all
but one of the indices missing. The case with all indices missing
doesn't work as the return data is too large, but the solution is known
to be `x^width - 1` in case we need to know.
