The function creates a new array representing a single minute chunk of data
with a given timestamp and data row.
@param currentTimestamp - A JavaScript Date object representing the
current timestamp.
@param currentNewData - The data row that needs to be added to the
minute chunk.
@returns an array containing the start and end timestamps of a minute
chunk, as well as a data row that fits within that minute chunk.
