Compilation Bug: Function Overloading Redundancy

For supporting decimal256 datatype, the Int128 datatype has been globally updated across the project. The previously used absl library has been deprecated in favor of proton's wide::Integer.

Now, the overload of the decimal Append function is ambiguous. When appending string type data to a decimal, the type must be explicitly specified for the compilation to succeed; otherwise, the following error will occur:

/home/kongsha/develop/timeplus-cpp/ut/client_ut.cpp: In member function ‘virtual void ClientCase_Decimal_Test::TestBody()’:

d1->Append(static_cast<std::string>("12345.6789")); is ok.
