/**
 * Imports configuration for the compiler.
 * Structure:
 * {
 *  "<compiled-path-prefix-1>": {
 *   "<import-path-prefix-1>": ["<import-path-1>", "<import-path-2>"],
 *   "<import-path-prefix-2>": "<import-path-3>",
 *   ...
 *  }
 *  ...
 * }
 * Import `import` written in file with path `path`
 * is resolved as follows:
 * 1. Try to resolve `import` as relative import from `path`
 * 2. If relative resolution failed:
 *  a. Find **the longest** <compiled-path-prefix>
 *     that is a prefix of `path` in the imports configuration
 *  b. In obtained map, find **the longest** <import-path-prefix>
 *     that is a prefix of `import`
 *  c. Replace prefix in `import` with <import-path>
 *  d. Try to resolve import with obtained path
 *     (try a few paths if array was provided)
 *
 * WARNING: <compiled-path-prefix> in 2.a is compared with
 *          absolute normalized path of `path`, so <compiled-path-prefix>
 *          should be absolute normalized path as well
 * NOTE: <import-path-prefix> could be empty string,
 *       in which case it will match any import
 * NOTE: passing just an array of strings is a shorthand for
 * {
 *   "/": {
 *     "": <array>
 *   }
 * }
