Dai Yokota / Mbed 2 deprecated TextLCD_ostream_sample

sample program using TextLCD_ostream

Dependencies:   TextLCD_ostream mbed

This is sample program using std::ostream with TextLCD
Because a large amount of memory is needed, it does not work in low memory MPU.
(It works fine on mbed LPC1768 and STM32 Nucleo-L476RG. But linker error occard on TG-LPC11U35-501)
