Feature request: tab-size classes

[silverwind]

It would be useful if tailwind had classes to set integer tab-size. For example:

• tab-size-2 -> tab-size: 2;
• tab-size-4 -> tab-size: 4;
• tab-size-8 -> tab-size: 8;

Units like tab-size-[1em] could be supported as well. Classes like tab-4 are already supported in unocss, albeit with unnecessary vendor-prefixes.
