/**
 * Handles parsing AsciiDoc attribute lists into a plain object of key/value pairs.
 * By default, attributes must each be separated by a comma and quotes may be used
 * around the value. If a key is not detected, the value is assigned to a 1-based
 * positional key. Positional attributes can be "rekeyed" when given a positionalAttrs
 * array either during parsing or after.
 *
 * @example
 * const attrlist = new AttributeList('astyle')
 * await attrlist.parse()
 * // => { 1: 'astyle' }
 *
 * attrlist.rekey(['style'])
 * // => { 1: 'astyle', style: 'astyle' }
 *
 * @example
 * const attrlist2 = new AttributeList('quote, Famous Person, Famous Book (2001)')
 * await attrlist2.parse(['style', 'attribution', 'citetitle'])
 * // => { 1: 'quote', style: 'quote', 2: 'Famous Person', attribution: 'Famous Person',
 * //      3: 'Famous Book (2001)', citetitle: 'Famous Book (2001)' }
