* Use PIO IRQ accessors in PIO I2C example
* Update pio/ir_nec/README.adoc file links (#183)
The "List of Files" now links (only) to files, not to directories (which prevented this example being included in the C SDK databook)
Bug fixes and new examples

adc/microphone_adc - Read analog values from a microphone and plot the measured sound amplitude.
i2c/bmp280_i2c - Read and convert temperature and pressure data from a BMP280 sensor, attached to an I2C bus.
i2c/lis3dh_i2c - Read acceleration and temperature value from a LIS3DH sensor via I2C
i2c/mcp9808_i2c - Read temperature, set limits and raise alerts when limits are surpassed.
i2c/mma8451_i2c - Read acceleration from a MMA8451 accelerometer and set range and precision for the data.
i2c/mpl3115a2_i2c - Interface with an MPL3115A2 altimeter, exploring interrupts and advanced board features, via I2C.
i2c/oled_i2c - Convert and display a bitmap on a 128x32 SSD1306-driven OLED display
i2c/pa1010d_i2c - Read GPS location data, parse and display data via I2C.
i2c/pcf8523_i2c - Read time and date values from a real time clock. Set current time and alarms on it.
uart/lcd_uart - Display text and symbols on a 16x02 RGB LCD display via UART
* This should make using the WS2812 examples a bit easier.
Moved parameters to the top as defines:
- Number of LEDs in your NeoPixel/WS2812 strip/ring
- Flag if the LEDs are WRGB or not
Changed PIN to 2 as pin 0 is used for serial UART.
The initial bit transition would be set even if the queue stalled.
The state machine still takes 16 cycles per bit
The next bit starts on state 1 and 9 instead of 0 and 8 so the timing is the same as before
