> TestNegativeCliDriver[compute_stats_long] intends to test fmsketch has a hard limit on number of bit vectors (1024). However, the test fails for the following wrong reason.

> Since this function is superseeded by compute_bit_vector_fm, it is best if we add the same test for compute_bit_vector_fm too.
