Mock IMU with previous flight data

[Graicc]

We should be able to feed previous flights (in the standard format) as mock IMU inputs. This will let us make sure the state machine will work on launch day, and ideally can be an automated test to make sure we never break anything.

The standard format:

data stored in blocks corresponding to the polling rate of each block (i.e. the number of rows for each block)

H1: Name of Rocket: brief description
H2: Rocket Parameters Names. Ordered:		Mass, Length, CG, CP, ...
H3: Rocket Parameter Values
H4: Data File Parameters Names. Ordered:    #Blocks, [#_row_block_1, #_col_block_1, #_row_block_2, #_col_block_2, ... for each block] ,...
H5:	Data File Parameters Values
H6:	Auxiliary information about data (info about IMU orientation... stuff like that)
H7:
H8:
H9:
H10: Names of Data Fields

Block Column Order:
Col_1 is always a Timestamp
 - then in order of the following priority
	- (all raw data) before (all estimated/calculated data)
	- within those groups
		pressure/altitude, accelleration, gyroscope(angular rate), orientation, GPS stuff

Standard names:
	time
	pressure
	altitude
	accel_x
	accel_y
	accel_z
	gyro_x
	gyro_y
	gyro_z
	pitch
	yaw
	roll
	quat_0
	quat_1
	quat_2
	quat_3

Standard Units: SI (metric)
