=============================
Header: '@',Cols,Rows,Number
User: Number*8 - user characters (up to 32)
Data: Sequence of bytes that ends with 0xF0:
0xxxxxxx - ASCII character itself (including user space <0x20)
100xxxxx - Repeat space 2...33 times (x+2)
1010xxxx - Skip 1...16 characters (0 means 16)
1011xxxx - GFX character itself (0xB0...0xBF)
110xxxxx - GFX character itself (0xC0...0xDF)
1110xxxx - Repeat next character 1...16 times (0 means 16) + 1 byte after that
1111xxxx - Extended GFX character itself, but
11110000 - End of the image/movie (0xF0)
11110001 - End of the frame that should stay for N/30 sec and start from row M
(0xF1 + 2 bytes N and M after that)
