/**
 * Transforms a given size value into a string. The format of the output string
 * can also be customized using the same digit info format as used when calling
 * the {@link formatNumber} function.
 *
 * ```
 * {minIntegerDigits}.{minFractionDigits}-{maxFractionDigits}
 * ```
 *
 * Additionally the output of the unit of the string can be adjusted using the
 * following tokens as described. However the format must always start with a
 * valid digit info format as it basically gets split and passed on to another
 * implementation!
 *
 * | Token  | Description                     | Example   |
 * | ------ | ------------------------------- | --------- |
 * | `UU`   | Full length unit name           | Kilobytes |
 * | `uu`   | Unit name abbreviation          | kB        |
 *
 * @param value  The number of bytes that is expected to be formatted into a readable string
 * @param locale The locale used for the number formatting
 * @param format The format to expect of the output (eg. '1.0-2 uu')
 * @param unit   Optional {@link ByteNumberUnit} the output should be display in. If not
 *               provided, the breakpoint for the respective units will be used to auto-
 *               format the expected unit (eg. `1024` will be formatted to `1 kB`, given
 *               the default format is used, since `1024 >= kB`)
