Refactor DateTime and TimeSpan humanization to use ToQuantity extension #205

[alimeziane]

I have add ShowQuantityAs option to timeSpan and DateTime humanization.

I added to TimeSpan and DateTime humanization the ability to choose using ShowQuantityAs display amounts by number or letter. My development is based on the existing features of ToWords() to avoid redudancies.
For example :
TimeSpan.FromDays(15).Humanize(2,showQuantityAs : ShowQuantityAs.Words) --> two weeks , one day
DateTime.Now.AddDays(12).Humanize(false,showQuantityAs : ShowQuantityAs.Words) --> twelve days from now

This PR has been sitting here for 2.5 years with no updates. I was going to review it but it also has too many conflicts now. I am closing it. Happy to review it once the conflicts are resolved @alimeziane.
