Logger Array Handling

[tkevinbest]

🚀 Feature Request

The logger doesn't handle arrays right now. It'd be great if it were smart enough to take an array and give each index its own column. For example, in the following code the acceleration field is an array of length 3.

log.add_attributes(cheap_IMU, ["acceleration"])
It would be great if the resulting log could be:
cheap_IMU_acceleration_0 | cheap_IMU_acceleration_1 | cheap_IMU_acceleration_2
