Bump version to 0.2.22

[ainyan03]

Patch release. Requires M5GFX 0.2.29 or later (the PoE-P4 display output takes the I2C port and pins in its config).

New API (additive)

• Speaker.setBufferReleaseCallback() / Mic.setBufferReleaseCallback(): notified when a queued buffer has been consumed, so several buffers can be rotated without polling (Add setBufferReleaseCallback to Speaker and Mic #356)
• Mic.setPostStartCallback() (StopWatch: recover ES8311 capture after power-on reset #348)

Fixes

• Tab5: the ESP-Hosted SDIO pins are set in M5.begin(), so WiFi works with the generic esp32p4 board selected; sketches without WiFi are not affected (Tab5: set the ESP-Hosted SDIO pins in M5.begin #358)
• CoreS3: external 5V output not turning off / re-enable being cancelled on USB-C without a battery (CoreS3: fix external 5V output not turning off / re-enable being cancelled on USB-C without battery #352)
• GPIO46 is restored after board detection on boards that expose it (camera on CoreS3) (Restore GPIO46 after board detection on boards that expose it to the application #345)
• StopWatch: ES8311 capture after power-on reset, and the ES8311 gain structure (mic noise / clipping, speaker distortion at high volume) (StopWatch: recover ES8311 capture after power-on reset #348, StopWatch: fix the ES8311 gain structure (mic noise/clipping, speaker distortion at high volume) #350)
• Mic_Class: record() and lifecycle changes are serialized without blocking end(); an explicit sample_rate of 0 now fails instead of being undefined (Mic_Class: serialize record() and lifecycle changes without blocking end() #351)
• StickS3: IMU axis orientation (Fix M5StickS3 IMU axis orientation #342, thanks @hlym123)
• BMI270: a failed config upload is reported instead of leaving the IMU marked as initialized; PCF8563: setTimerIRQ() rounding no longer overflows near UINT32_MAX (BMI270: report a failed config upload; PCF8563: setTimerIRQ rounding does not overflow #361)
• I2C_Class prefers driver/i2c_master.h over the legacy driver/i2c.h (I2C_Class: prefer driver/i2c_master.h over the legacy driver/i2c.h #355)
• Built as an ESP-IDF component, the Arduino component is linked automatically (Link the Arduino component automatically when built as an ESP-IDF component #344)

Examples

• The audio examples share AudioUI.h / AudioOutputM5Speaker.h; the MP3 example also plays WAV (Share the display and input handling of the audio examples; MP3 example plays WAV #357)
• MP3 and Speaker_SD_wav_file mount the card as 4-bit SD_MMC where the board wires it (Tab5), SPI elsewhere, with the pins from M5Unified; WebRadio selects STA mode before disconnect() (MP3 example: mount the card as 4-bit SD_MMC where the board wires it, SPI elsewhere #359, Examples: Speaker_SD_wav_file mounts the card like the MP3 example; WebRadio selects STA mode before disconnect() #360)

Merge after #363.
