Function phron_finality::metrics::exponential_buckets_two_sided

fn exponential_buckets_two_sided(
    start: f64,
    factor: f64,
    count_below: usize,
    count_above: usize
) -> Result<Vec<f64>>

Create count_below + 1 + count_above buckets, where (count_below + 1)th bucket has an upper bound start. The buckets are exponentially distributed with a factor factor.
