Array of bytes to string

[eightyfive]

Using a table with the 256 bytes as strings, said table is used as a reference in the 2 functions of this code. Functions who make the conversion such as the title establishes, and in the inverse way too.

The main adventage is that you don't need any knowledge about managing bytes with c++..
