enumerateTrackTitles.js

/**
 * - Renames all tracks using their absolute track number and a customizable prefix (which can be empty).
 * - Useful to number the parts of an audiobook without chapters and other releases with untitled tracks.
 * - Asks the user to input a numbering prefix which can optionally be preceded by flags:
 *   - Append the number (including the given prefix) to the current titles: `+`
 *   - Pad numbers with leading zeros to the same length: `_`
 *   - *Example*: `+_, Part ` renames track 27/143 "Title" to "Title, Part 027"
