/**
 * Wraps an HTML <select> component to act as a time selector, and automatically generates incremented options between
 * a min and max time, given an increment in minutes.
 *
 * If the max value does not occur naturally from increments of the min value, it will be added as the last option.
 *
 * Attributes:
 *   min (required): An ISO 8601, Python "naive", or Python "aware" formatted datetime string representing the first
 *                   possible time option
 *   max (required): An ISO 8601, Python "naive", or Python "aware" formatted datetime string representing the last
 *                   possible time option
 *   step (optional): A numeric value representing the option value increment in minutes. Defaults to 15.
 *   label-format (optional): A Luxon format string to use for formatting the text of the options. Defaults to "h:mm a"
 *                            (1:30 PM)
 *   placeholder (optional): A string label to use as a placeholder for an empty value. Defaults to an empty string.
 *                           No empty value placeholder is added if the field is required.
 *   value (optional): An ISO 8601, Python "naive", or Python "aware" formatted datetime string representing the initial
 *                     value
 *
 * Usage:
 * ```html
 *   <iw-time-selector required min="2020-11-03T08:00:00.000" max="2020-11-03T016:00:00.000" value="2020-11-03T12:00:00.000" increment="15" label-format="h:mm a" />
 * ```
