This change can allow the programmer to override Nan/Infinity/-Infinity to be not only NaN but null, 0 or whatever they want it to be.

This change modifies the
json.encodermodule to permit customization of how special floating-point values (NaN,Infinity,-Infinity) are serialized. By introducing afloatstrfunction, developers can now define alternative representations for these values, such asnull,0, or custom strings, enhancing flexibility in JSON output.
