Summary
This PR is refactoring of SigmaDelta HAL in order to use IDF instead of current Register manipulation approach.
Impact
Change in API:
uint32_t sigmaDeltaSetup(uint8_t channel, uint32_t freq);
changed to -->
uint32_t sigmaDeltaSetup(uint8_t pin, uint8_t channel, uint32_t freq);
void sigmaDeltaAttachPin(uint8_t pin); removed, no longer needed. Pin is attached in sigmaDeltaSetup()
This is very much still work in progress and much more will change before the final 2.0.0
Some APIs have changed. New libraries have been added. LittleFS included.

* Add APB change callbacks and move cpu code to own file
* Properly set esp_timer and FreeRTOS tick dividers
* Improve updated devisors
* No need to update REF_TICK yet
* Add initial handling for UART baud change
* fix uartWriteBuf and uartDetectBaudrate
* trigger callbacks even when APB did not change
* toggle UART ISR on CPU change
* add XTAL freq getter and add cpu freq validation
* Support CPU frequency changes in I2C (#2287)
**esp32-hal-i2c.c**
* add callback for cpu frequency changes
* adjust fifo thresholds based on cpu frequency and i2c bus frequency
* reduce i2c bus frequency if differential is too small
**Wire.h**
* version to 1.1.0
* Implement clock change for the other peripherals
* remove bad CPU clock values from the menu
* Add note to CPU freqs that support WiFi and BT
* Add support to HAL for APB frequencies different than 80MHz
* Add support for CPU frequencies in the IDE board menu
* Switch to fast set_config
* Add method to uart so debug can be reassigned after apb frequency switch
* Return real APB frequency
The esp-idf expects duty values for the the sigma delta modulator in the range of -128 to 127
The arduino framework is supposed to use the range 0-255 thus the offset caclulation was wrong.
