More than 100 Koti is not handled

[m4hi2]

Calling to_bn_word(111111111110) results in crashing the program.

>>> main.to_bn_word(111111111110)      
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/home/m4hi2/number-to-bengali-word/number_to_bengali/main.py", line 17, in to_bn_word
    generated_words = whole_part_word_gen(whole_segments)
  File "/home/m4hi2/number-to-bengali-word/number_to_bengali/utils.py", line 58, in whole_part_word_gen
    generated_words += numeric_words[str(segments[segment])] + \
KeyError: '11111'

Expected Output: এগারো হাজার এক শত এগারো কোটি এগারো লক্ষ এগারো হাজার এক শত দশ

Hint on how to fix:
if the segment of koti is more than 100, run generate_segments() on that and generate the words then add to the rest of the words. Should be simple fix, feel free to ask if you anything.
