mtlb_fwrite Matlab fwrite emulation function

## Description

There is no Scilab equivalent for Matlab `fwrite`. Scilab `mput` and Matlab `fwrite` behave differently in many cases, but they are equivalents in some cases.

The function `mtlb_fwrite(varargin)` is used by `mfile2sci` to replace `fwrite`. This function will determine the correct semantic at run time. It is sometimes possible to replace calls to `mtlb_fwrite` by calls to mput.

Caution: `mtlb_fwrite` has not to be used for hand coded functions.
