Recheck header and 3c-code dimensions

Header writing issue

• Rebuild the way header is written according to the 3c-code building instructions

3C-Code dimensions

Review 3C-Code dimensions to match the following constraints

• header must be separate by the debugging landmark (red line, 135°th degree), making one column from each side
• implement different formats to make 3c-code able to fit smaller data to the biggest (reach at least 1KB)
