MD060 feature request: autofix

[afeblot]

The "aligned" table mode is the easiest / most readable mode in the raw markdown files.
However, tables containing emojis are pretty difficult to align manually, and the vscode extensions such as https://marketplace.visualstudio.com/items?itemName=TakumiI.markdowntable which usually automatically aligns table columns also fails handling these tables with emojis properly.

The easiest way for users would be for markdownlint to immediately update table alignments according to the mode configured for MD060.

+1 tight, compact are also unambiguous. autofixing would be great

I published a custom rule for this: https://www.npmjs.com/package/markdownlint-rule-table-format

Supports all table styles, including "aligned" which we use in our project, and I just updated it to work properly with emoji and CJK characters.

I was frustrated it wasn't fixable by markdownlint when yzhang's markdown-all-in-one can fix tables when using the extension and formatting on save is enabled. I even provided a link to that extension's source code that performs the table formatting to help David possibly implement the fixing function but it never materialized.

I have a couple other files I'm working on for fixing MD036/no-emphasis-as-heading and MD040/fenced-code-language, but those aren't done quite yet. MD040 just turns any empty code fences
