[NUC240] Implement ADC Median Filter

[chhsieh3]

• Application: The example code implements ADC sampling noise reduction by using Median Filter.
• BSP Version: NUC230/240 Series BSP CMSIS v3.01.001
• Hardware: NuEdu-EVB-NUC240 v1.0

The sample code implements a simple ADC sampling noise reduction with Median Filter. Do five times ADC sampling and then sort the values. Use Median Filter to takes the number in the middle of the sorted values.
