Uninformative bad date error

[bholtdwyer]

Just a quick note: I found that if you mistakenly input an invalid date (like September 31), landsat_search just prints "Error: 400" a bunch of times. As a suggestion, it might be worth doing some basic validation on the date inputs so that an error such as "Date does not exist" can be returned. Thanks for this very useful package!

result = landsat_search(min_date = "2002-09-01", max_date = "2002-09-31", country = "Indonesia")
