lsd does not exit on closed pipes

[PythonCoderAS]

• os:
• lsd --version: lsd 0.21.0
• echo $TERM: xterm-256color
• echo $LS_COLORS:

zsh: correct '$LS_COLORS' to '$LSCOLORS' [nyae]? y

Expected behavior

When piping to a program that exist, lsd will continue running until reading (all) paths is done. This is a problem when using the recursive flag, as lsd will recurse all directories than exit.

lsd -lR / | bash -c 'exit'
```: This command will go on until all paths are consumed, which takes a lot of time and memory.

```bash
/bin/ls -lR / | bash -c 'exit'
```: This command exits in less than a second.

## Actual behavior
