[Feature]: Ability to negate boolean options on the command-line

### Version

- [X] latest

### version

lsd 1.0.0

### What OS are you seeing the problem on?

Linux

### installation

`pacman -S lsd`

### term

`xterm-kitty`

### ls-colors

`` (empty)

### What happened?

It's cool to be able to use `header: true` in the config. However, this denies me the ability to have `lsd` list files without a header.

### What expected?

It would be great to be able to negate the `--header` option, and ideally all other boolean options (if it makes sense at least).

### What else?

A mere suggestion, but I think a simple and consistent formula would be best. Wherever applicable, each boolean long option would have a negative version prefixed with `no-` (e.g. `--header` → `--no-header`), and each boolean short option can be negated by prefixing it with a plus. `lsd -l` → `lsd +l`.
