* Update sol1.py

* Fix: use proper path to open files
* Commit suggestions:
- Use list comprehension instead of map
- Sort imports using isort
* Changes made as suggested (simplified a lot):
- List and set comprehension instead of itemgetter
- Using enumerate as it's easy to read
- Divided into list of card values and set of card suit as set will
remove all the duplicate values. So, no need for double indexing.
- Add test for testing multiple calls to five_high_straight function
* Add suggestions and simplified:
- Split generate_random_hands function into two:
- First will generate a random hand
- Second, which will be called, will return a generator object
