MAX_TEXT_LEN is automatically selected based on the LORA_CR build flag
defined in platformio.ini (e.g. -D LORA_CR=5).
CR4/5: 48 bytes (~16 JP chars, TX ~3808ms)
CR4/6: 32 bytes (~10 JP chars)
CR4/7: 24 bytes (~8 JP chars)
CR4/8: 16 bytes (~5 JP chars, default)
To enable CR4/5 for Japan, add -D LORA_CR=5 to your board's
build_flags in platformio.ini. Set LORA_CR=5 for WioTrackerL1 and RAK WisMesh Tag.
JP_STRICT limits MAX_TEXT_LEN to 1*CIPHER_BLOCK_SIZE (16 bytes) to keep
TX time under 4 seconds on SF12/BW125/CR4-8 (Japan LoRa settings).
SF12/BW125/CR4-8 airtime:
60 bytes total packet = ~3809ms (within 4s limit)
packet overhead ~44 bytes, leaving 16 bytes for text payload
Enabled only for WioTrackerL1 and RAK_WisMesh_Tag builds.
Sensors connected via the Grove I2C connector (D18/D17) were not detected
because the firmware scanned the OLED I2C bus (Wire, D14/D15) by default.
Adding ENV_PIN_SDA/SCL flags directs EnvironmentSensorManager to use Wire1,
matching the physical Grove connector pinout.

As all NRF52 boards now have OTA support, let's remove the subclass
and integrate it into the base class.

The startOTAUpdate() is the same for all NRF52 boards. Use a common
implementation for all boards that currently have a specific
implementation.
The following boards currently have an empty startOTAUpdate() for
whatever reasons and therefore are not inheriting NRF52BoardOTA to
keep the same state: Nano G2 Ultra, Seeed SenseCAP T1000-E,
Wio WM1110.

Some NRF52 boards are able to use the internal power-efficient DC/DC
regulator. Add a new class that can be inherited by board classes to
enable this feature and reduce the power consumption.

Use a common begin() method that can be called from derived classes
to contain the shared initialization code.

* MomentaryButton: new constructor 'multiclick' param
* WIoTrackerL1: now just use joystick, joystick press for KEY_ENTER, no multi-click for snappier UI
