BMP convertor class.
Completely native implementation, doesn't use external libs.
memfs is used differently here, therefore the class is derived
directly from r_Convertor rather than r_Convert_Memory.
Supported parameters are
\begin{tabular}{lcl}
compress && int && Use compression (8bpp only)
\end{tabular}
