EnviroDIY/ModularSensors: v0.33.0

Changed Breaking: Renamed the static markedEpochTime variable to markedLocalEpochTime. This was sometimes used in "complex" loops. Code utilizing it will have to be changed. This is part of the effort to clarify where localized and UTC time are being used. We recommend a logger's real time clock always be set in UTC and then localized for printing and storing data. Breaking: Renamed the function setNowEpoch(uint32_t) to setNowUTCEpoch(uint32_t). Although public, this was never intended to be used externally. Breaking: Renamed the YosemiTech Y550 COD sensor as Y551. See below. Potentially Breaking: Changed the default "button" interrupt pin mode from INPUT_PULLUP to INPUT and created optional arguments to the setTestingModePin and setLoggerPins functions to specify the pin mode and pull-up resistor state. INPUT is the proper mode for the Mayfly. The Mayfly has an external pull down on the button pin with the button being active high. This means having the pull-up resistors on negates the button signal. The pin mode had been set as INPUT_PULLUP for the button, backwards for the Mayfly, since July of 2017. By some electrical luck, with the 0.x versions of the Mayfly, the external pull-down on the button pin was strong enough to out-weigh the incorretly activated pull-up resistors and an interrupt was still registered when the button was pressed. With a different pull-down resistor on the Mayfly 1.x, the button no longer registers with the pull-up resistors active. So, for most of our users with Mayflies, this will be a fix. But for anyone using a different board/processor/button configuration that depended on the processor pull-up resistors, this will be a breaking change and they will need to specify the button mode in the setTestingModePin or setLoggerPins function to return to the previous behavior. Added a longer warm up time and removed some of the modem set-up to work with the ESP-IDF AT firmware versions >2.0 Made sure that all example clock synchronization happens at noon instead of midnight. Renamed Classes: Renamed several classes for internal consistency. These are not breaking changes at this time; the old class names are still usable. Rename class MPL115A2 to FreescaleMPL115A2 Rename class MPL115A2_Pressure to FreescaleMPL115A2_Pressure Rename class MPL115A2_Temp to FreescaleMPL115A2_Temp Rename class TIINA219_Volt to TIINA219_Voltage Rename class PaleoTerraRedox_Volt to PaleoTerraRedox_Voltage Rename class ExternalVoltage to TIADS1x15 Rename class ExternalVoltage_Volt to TIADS1x15_Voltage Documentation: Migrated to latest version of Doxygen (1.9.3). Added Sensor Added support for the YosemiTech Y551 COD Sensor, which makes a UV254 light absorption and translates it to estimates of Chemical Oxygen Demand (COD) (or Total Organic Carbon (TOC)) and Turbidity. NOTE that this upgrade removes the earlier Y550 from the library, as it was never tested and is no longer available form YosemiTech. If anyone has a Y550 sensor, the Y551 commands should work. Let us know if they don't. Sensor Added support for the YosemiTech Y560 Ammonium Probe, which is a mini sonde for three Ion Selective Electrode (ISE) sensors (pH, NH4+, K+) that together are used to provide a corrected estimate of total ammonium nitrogen (NH4_N) in mg/L. NOTE that this release only includes outputs for NH4_N, pH, and temperature. A future release will also include estimates of potassium (K) and raw potential values from each of the electrodes. Sensor Added support for the SDI-12 In-Situ Level TROLL 400, 500 & 700 Data Loggers Sensor Added support for the Sensirion SHT40 relative humidity and temperature sensor Sensor Added support for the Everlight ALS-PT19 ambient light sensor Sensor Added support for the Bosch SensorTec BMP388 and BMP390 pressure sensors Removed Fixed Fixed memory leak for AOSong AM2315 thanks to @neilh1
