docs: Get the actual indent of node
  @param {ASTNode|Token} node Node to examine
  @param {boolean} [byLastLine=false] get indent of node's last line
  @returns {Object} The node's indent. Contains keys `space` and `tab`, representing the indent of each character. Also
  contains keys `goodChar` and `badChar`, where `goodChar` is the amount of the user's desired indentation character, and
  `badChar` is the amount of the other indentation character.
