TODO

• Implementing reading image in bmp format in util/fileio.cpp (can refer WriteImageBMP():util/fileio.cpp)

• isnan() in pstd/math.h is implemented by a call to __builtin_isnan(), we should be able to do it ourself by comparing the bit pattern of the input floating-point number with bit pattern of nan number(https://docs.microsoft.com/en-us/cpp/build/ieee-floating-point-representation?view=msvc-170#nan---not-a-number)
