EDID 1.4: Trivial support for new detailed sections.

Nothing actually decoded yet, but at least we print what they are.

New in EDID 1.4:
- Color Management Data (0xF9), Section 3.10.3.7
- CVT 3 Byte Code Descriptor (0xF8), Section 3.10.3.8
- Established Timings III Descriptor (0xF7), section 3.10.3.9
- Manufacturer-specified data tag (0x00 - 0x0F), section 3.10.3.12
