add write utils

[daehuikim]

When I use deepeval with massive data without web application, It is difficult to track every results from the printed logs.
To address this, I hope to add file writing functions on the utils to get log for evaluation.
This function even helps to track missing data by connection errors.

hey! @daehuikim can we put this in display config? thanks!

[daehuikim]

@penguine-ip Yes please. :)
I noticed my commit is missing adding variable in display_config.
I will make extra commit about this. <= Done

Hey @daehuikim thanks for changing it, i was hoping to have everything in utils. An optional file_output_dir would be great for the display config, what do you think?

[daehuikim]

@penguine-ip Can you confirm the change from the last commit please? I hope I am on the right way.
I just made file_output_dir in the DisplayConfig and everything is happen in the utils.py
