spec: SQLite Database File Format, section 1.3

Exactly the ASCII string 'SQLite format 3' (15 bytes) plus a trailing NUL (0x00) = 16 bytes at offset 0.
Byte 16 onward continues the database header (page size at offset 16, etc.).
The extension is conventional only; SQLite does not require any particular filename.
