ByteColorScheme class

Color scheme for syntax highlighting different byte types in the hex viewer.

This class defines colors for various byte categories to provide visual cues about data content:

Null bytes (0x00) - typically shown in gray
Printable ASCII (0x20-0x7E) - regular text characters
Control characters (0x01-0x1F) - shown in red to highlight special bytes
Extended ASCII (0x80+) - shown in blue for non-standard characters

Example:

// Use predefined schemes:
const lightScheme = ByteColorScheme.standard();
const darkScheme = ByteColorScheme.dark();

// Auto-adapt to app theme:
final scheme = ByteColorScheme.fromTheme(Theme.of(context));

// Custom colors:
const custom = ByteColorScheme(
  nullByte: Colors.grey,
  printableAscii: Colors.black,
  controlChar: Colors.red,
  extendedAscii: Colors.blue,
  selectedBackground: Colors.blue,
  selectedForeground: Colors.white,
);
