Description

check for bucket instead of the bucket index

It was incorrectly checking for index

for i in range(len(buckets)):
    obs_freq[i] = (sample_bucket_ids == i).sum()

It should be checking for the value at the index

Bucketing for discrete and continuous distributions is different and hence has to be handled differently.

Moreover this change passes the verify_generator tests for both discrete distribution (randint) as well as continuous ones (normal, uniform, ... etc)
