`preferAttrsSingleLine`

Control whether attributes should be put on single line when possible.

This option conflicts with maxAttrsPerLine option.

Default option is false.

Example for `false`

This <div> is short enough to be put on single line, but it won't because attributes in source code span multiple lines.

<div
  data-a
  data-b data-c
></div>

will be formatted as:

<div
  data-a
  data-b
  data-c
></div>

This <div> is short enough so it will be put on single line though attributes span multiple lines in source code.

<div data-a
  data-b
  data-c></div>

will be formatted as:

<div data-a data-b data-c></div>
