Обновление до версии 0.3.0

- обновлен elbear_fw_bootloader - добавлена проверка контрольной суммы каждой строки hex файла.
- в модуль работы с АЦП добавлена функция analogReadResolution(). Функция analogRead() теперь возвращает усредненное по 10 измерениям значение.
- общая функция обработки прерываний перенесена в память RAM. Обработчики прерываний модулей External Interrupts и Advanced I/O (функция tone()) так же перенесены в память RAM для увеличения скорости выполнения кода.
- в пакет добавлены библиотеки EEPROM, Servo, SoftSerial, NeoPixel, MFRC522 адаптированные для работы с платой Elbear Ace-Uno.
- добавлено описание особенностей работы с пакетом
