Changes to api/sensors/flashlog POST data from BEEP base fw 1.5.0+ FLASH log (with timestamp), interpret data and store in InlfuxDB (overwriting existing data). BEEP base BLE cmd: when the response is 200 OK and erase_mx_flash > -1, provide the ERASE_MX_FLASH BLE command (0x21) to the BEEP base with the last byte being the HEX value of the erase_mx_flash value (0 = 0x00, 1 = 0x01, i.e.0x2100, or 0x2101, i.e. erase_type:"fatfs", or erase_type:"full")
