Add MinimumInlineWidth to TomlNode.

[gibbed]

Supported by TomlArray and TomlTable.

I don't know if such a feature would be desired upstream.

The goal is fine-grained control over spacing when writing inline tables, to better format output for human consumption.

So you can do something like this:

rows = [
  { id = 0,   title = "foo" },
  { id = 10,  title = "bar" },
  { id = 100, title = "baz" }
]

By setting MinimumInlineWidth to 3 on each TomlNode for id.
