ADS Actions on TI AFE4403

added JTAG debug interface and UART interface on TI AFE4403 EVM;

finish porting static algorithm of HRM to MSP430F5528 on TI AFE4403 EVM;

optimized the static algorithm of HRM based on the source code released by TI, we can get more accurate value;

User can get the test result through UART with TI AFE4403 EVM.

Test Environment--- Azumio APP
