Increase the function of memory conversion

[kekxv]

add c_vector

can read and write Memory stream

Support j2k conversion to bmp or raw using memory stream

[kekxv]

Useful on some embedded systems that do not support file writing

This project is relatively large, I just need to use the memory stream method for conversion, so I provide a method to convert j2k to bmp. As for the others, I have no further research.
