[File Tree Generator] Configurable Indentation

Description

Currently, the output returns indentations of 4 characters: whatever combination of bar, up+right, vert+right is needed as well as 2 spaces or "left" bars.

This results in perfectly fine "trees" but some users may prefer something a little bit more horizontally compact. The new configuration option would provide this to such users.

Behind the scenes, this would be achieved by reducing the number of spaces and "left" bars from 2 to 1.

For example, from file-tree-generator/src/line-strings.ts :

    CHILD: "├── ",
    LAST_CHILD: "└── ",
    DIRECTORY: "│   ",
    EMPTY: "    ",

instead, the strings could be:

    CHILD: "├─ ",
    LAST_CHILD: "└─ ",
    DIRECTORY: "│  ",
    EMPTY: "   ",

The difference in output would look like this: Default (4 spaces)

root
├── level1
│   ├── level11
│   └── level12
├── level2
└── level3

Can be reduced to: 3 spaces

root
├─ level1
│  ├─ level11
│  └─ level12
├─ level2
└─ level3

Who will benefit from this feature?

Anyone who would prefer a more compact tree.

Anything else?

The easy—but non-intuitive from a UX perspective—way to implement this would be to simply add "3 space alternatives" in the "Charset" options. e.g.:

Charset:
- UTF-8 Default Indent
- UTF-8 Narrow Indent
- ASCII Default Indent
- ASCII Narrow Indent

Proper way would be to

1. Figure out the UI language and affordances and add them as part of the UI. e.g.: Set indentation depth: Wide (default) / Narrow
2. a) Reflect the possibilities in the const LINE_STRINGS or
3. b) Generate the LINE_STRINGS based on the selected configuration (maybe overkill…)
