feat: Add start and end positions of tag nodes

[Alteras1]

Adds start and end position of the start/end of tag nodes. This gives developers more control in debugging issues. This also allows developers to perform manual string manipulation beyond the limitations of the parser.

'[bar]Foo Bar[/bar]'

will parse to:

[
  {
    tag: 'bar',
    attrs: {},
    content: ['Foo', ' ', 'Bar'],
    start: {
      from: 0,
      to: 5,
    },
    end: {
      from: 12,
      to: 18,
    },
  },
];

An example of string manipulation usage

const str = '[font=Source Sans 3]text[/font]'

parses to:

[
  {
    tag: 'bar',
    attrs: {
      3: "3",
      "Source": "Source"
      "Sans": "Sans"
    },
    content: [text'],
    start: {
      from: 0,
      to: 19,
    },
    end: {
      from: 23,
      to: 29,
    },
  },
];

Since quotes was not used and there is a single integer by itself, recovering the original full single value would be impossible without using string manipulation.

const isSingleValue = (attrs) => {
  const keys = Object.keys(attrs).join(" ");
  const vals = Object.values(attrs).join(" ");
  return keys === vals;
}

font: (node) => {
  let value = '';
  if (Object.values(node.attrs).length > 1 && isSingleValue(node.attrs)) {
    value = str.substring(node.start.from + 5, node.start.to - 1).trim();
    // value = "Source Sans 3"
  }

  ...
}

Improves accuracy of row/col error reporting. Now targets the start of the relevant token instead of the end.

Closes #134
