Feature: Byte Dump should print the first and last range.

Providing the `--first` and/or the `--last` parameters should then put the range in the title.

The range is inclusive for the first character and exclusive for the last character.
Therefore, the `[` character is used for a closed range for first and `)` character is used for an open range for the last.
