Mistake in maths/average_mode.py fixed. (#4464)
A serious bug was addressed with this pull request. The mode function previously
didn't return the mode of the input list. Instead, it always returned the first value.
Due to lacking tests, the bug was never caught. This pull request also adds new
functionality to the function, allowing support for more than one mode.

See #4464 for details.

* * Mistake in average_mode.py fixed. The previous solution was to returnthe
value on the first loop iteration, which is not correct, more than that it
used to delete repeating values, so result's array and check array lost
relation between each other

* Type hint added

* redundant check_list deleted

Co-authored-by: Maxim R. <49735721+mrmaxguns@users.noreply.github.com>

* Suggestions resolved

* output typing changed to Any
* test cases added

* Black done

* Unused statistics import
