1. Инициализация hal библиотек, включение тактирования портов, установка вектора прерываний теперь производится в crt0.S 2. Добавлена библиотека IRremote. Для работы использует прерывание таймера timer16_0 Co-authored-by: KLASSENTS <klassen@elron.tech> Co-committed-by: KLASSENTS <klassen@elron.tech>
