Feature: Ability to hide line count for specific blocks using `ignore` flag

[Aetherinox]

One of the older codeblock-styler plugins had the ability to remove the line numbers per each codeblock, and I've not seen such a feature for this one.

In some codeblocks, I add shell commands instead of code, so there's really no use for having numbered lines.

But as it currently sits, all codeblocks enforce line numbers.

This functionality was available in the codeblock-styler plugin by adding the ignore flag to the codeblock.

```shell ignore
/bin/sh ps aux
```

When applying ignore, all you saw was a simple box with the command and syntax highlighting, but no language, no line numbers, etc. Just a copy button.

The only way to get this effect now with the Codeblock Customizer plugin is to combine it with the Obsidian Tabs plugin:

If you want to remove the line numbers, you can do that with ln:false as described in the parameters of the README. If you want tabs, you can do that with the groups parameter.
