2 improve time operators performance (#7)

* Improved time operators performance, refactored get_frequencies and find_min_frequency class methods.

* TimeHandling code cleaned.

* TimeHandling exceptions changed to SemanticError exceptions.

* Added new time semantic exception messages.

* Time operators timeshift class optimized.

* re-added old exception messages on TimeHandling.py, minor changes on Time.py.

* Cleaned some imports.

* Cleaned some imports.

* Added flake8 and black.

* Removed flake8 and black from this branch.

* Added usage of map instead of apply in get_frequencies on class Shift_dates.

* New time semantic error messages code changed to 2-1-19-X.
