Fix load_transactions() newline bug

[ZaxR]

load_transactions() currently iterates through characters in the input_file string. Example of the issue can be found here: https://stackoverflow.com/questions/43348498/using-the-load-transactions-function-in-the-apyori-package-in-python/46651675#46651675 . Explicitly defining newline fixes the issue. Also utilized context management.

Thanks for your request, but your changes doesn't satisfy the tests because load_transaction() can't take file-like objects... In my opinion, load_transaction() should be able to takes a file-like object as the csv.reader() do, even if it can also take a file path.

For the case in the Stack Overflow, opening file externally and giving the file object to load_transaction() can solve that problem as below.

with open(file_path) as file_obj:
    transactions = load_transaction(file_obj)

Thanks for the fast response - that makes sense. For users less familiar with the duck typing nature of python, would it make sense to offer a load_transactions_from_file() method that's just a wrapper for load_transactions()? Alternatively, adding your snippet above to the readme would be awesome, I think. Thank you for the package and support!

P.S. I updated my response to the SO question to include your answer.

I'm very sorry that I've forgot to reply... and thank you for your SO answer! Though your offer to implement load_transactions_from_file() makes sence, I have another idea that load_transaction() open and load a file when given a PathLike object (strings or bytes too). Does it help?
