add measurmentCycle and burstCycle to log, fix memory leak in drivers

[kenchong48]

• fix: change getconfiguration to return config json, comment out enough code (commands, serial messages) to fit co2 sensor driver
• fix: correct logic for checking against max sensor slots
• fix: correcting code commented out to fit co2 sensor driver
• fix: location of sensor driver[i]->setup, during wake cycle to be after i2c is reenabled
• feat: testing battery voltage, commented out some extraneous code
• fix: enable summary clear on burst start, implement summary for all drivers
• fix: change getconfiguration to return config json, comment out enough code (commands, serial messages) to fit co2 sensor driver
• fix: co2 sensors having i2c bus issues currently, in process
• feat: implement warmup functions in CO2 and DHT22 drivers, and check in datalogger loop; fix human timestamp; hardcode battery to exADC port 3, reimplement sensor reading interval and functions, implement rtc set time and diff delay when setting
• fix: final methaneV1 being tested
• fix: subtract the amount of time a reading takes from the inter reading delay, subtract the amount of time a burst cycle takes from the inter burst delay, correct the sensor warmup loop
• fix: add some notes to dht22 pins
• fix: add code to handle if no sensor provides a requested reading delay and TODO to clean up the logic later
• feat: improve debug to file feature when deployed
• fix: storing final changes before merge
• fix: memory leak in drivers (stop functions need delete), lowered flash memory consumption of messages, debug to file enabled, potentially final code for deployments
• feat: add measurement cycle and burst cycle counts to log output, shrink code to fit
• fix: shrink some messages, add delete externalADC for memory leak
