add auto cpu frequency
...
When this feature enabled:
* Frequency sets to 14MHz on esxdos activity - for fastest loading from
sd card;
* Frequency sets to 14MHz on 48 BASIC startup;
* Frequency sets to 3.5MHz within ~1ms after #FE port access - this
allows to load from tape within turbo mode. Also this improves beeper
sound effects;
* Otherwise user configured frequency is used.
