[C++] Implement cast from date32[day] to utf8

[asfimport]

I'm writing bindings between the C++ write CSV functionality and R.  When I test my code on a table with no dates columns, the tests pass, but when I test the code with a table that includes dates, I get the following error message:

Error: NotImplemented: Unsupported cast from date32[day] to utf8 using function cast_string

Code that causes error: #10141
