Feature/data pack

[Mira-Chronos]

• Step to step, DataPack construction with SDL2 primitives
• Prototype test program by example
• Commented code

DataPack

A DataPack is composed by an header and data

Header

The header is organized like this

• title: on 4 bytes
• number of files: on 2 bytes (uint16_t) One line for each file that contains
• its identifier on 40 bytes
• its position in the data : offset on 4 bytes (uint32_t)
• the size of the file : sizeFile on 4 bytes (uint32_t)

Data

Data are organized like this file0 offset 0 to 0+sizeFile0 <-- offset1 file1 offset offset1 to offset1 + sizeFile1 <--- offset2 file2 offset offset2 to offset2 + sizeFile2 <--- offset3 file3 offset offset3 to offset3 + sizeFile3 <--- offset4 ...
