АЛГОРИТМ:
- читаем весь файл в память
- детектим тим пубтитров по первым 512 байтам. Пробегаем побайтово по данным, для каждого из форматов субтитра.
- тот формат, который оказался _первым_ и есть искомый формат.
- если НЕПУСТЫЕ субтитры пересекаются, надо склеивать их (проверять в отдельном проходе).
- если 2 субтитра идут в одно и то же время, то надо показывать их по очереди кадр за кадром (а не все сразу)
  (некоторые субтитры в файлах - с точностью до секунды, и происходят накладки)
- работаем примерно так:
  1) задаём фильтр для поиска записи в виде набора лексем (массив).
    - лексема = набор спец.символов маски:
       0 = число
       1 = 1 цифра
       2 = 2 цифры
       ...
       " " = пробел
       \n = \n
       - строка?
    - для каждой лексемы задаём: 
     - как трактовать значение
       - никак
       - секунда начала
       - минисекунда конца
       - дельта времени начала
       ...
     - флаги
       - обязательно ли должна присутствовать
       -
