这段代码完成从7BIT压缩编码的数字字符串到ASCII码流的转换
透传模式并且DCS为7bit编码格式，用户输入每一个USSD数字，经过7Bit压缩后，
每个字节的高4bit和低4bit在此处是分别由一个Byte表示的
TAF接收到的用户USSD字符串就是2个字符表示一个数字，最大长度为320字符，
USSD空口码流容量为160BYTE，160BYTE 传输7BIT编码的字符，可以传输182个字符，
示例:
用户输入*199#的情况，应用接收到ASCII码流2A 31 39 39 23，进行7BIT编码后为
aa 58 2e 37 02，转换为数字字符串为61 61 35 38 32 65 33 37 30 32，通过AT命令
AT+CUSD=1,"61613538326533373032",15 AT透传"61613538326533373032"到TAF，所以
本函数输入: 61 61 35 38 32 65 33 37 30 32
本函数输出: ASCII码流为2A 31 39 39 23，长度为5
实现步骤:
1) TAF_AsciiNum2HexStr: 61 61 35 38 32 65 33 37 30 32 => aa 58 2e 37 02
2) MN_UnPack7Bit: aa 58 2e 37 02 => 2A 31 39 39 23
因为此处的ASCII码属于标准ASCII码，所以USSD的字符转换表对输出字符串无影响
16进制表示的USSD码流字符串转换为16进制表示的USSD码流
举例说明:
16进制表示的7BIT字符表压缩编码的USSD码流字符串 0x61 0x61 0x35 0x38 0x32 0x65 0x33 0x37 0x30 0x32
转换成
16进制表示的7BIT字符表压缩编码的码流 0xaa 0x58 0x2e 0x37 0x02
其中，0x61表示ASCII码的a 0x65表示ASCII码的e
