add SCRIPT_allan_txtparallel.m (Without building bagconvert)

[zerolover]

Build bagconvert a little bit complicated, so I write a script only use imu.txt

Do you have an example file that I could upload for people to test with?

[zerolover]

Sure, I upload the simulated imu data and result to google drive~ Here is the link int imu_frequency = 200; // Hz double gyro_noise_sigma = 0.000224; // rad/s double gyro_bias_sigma = 0.000005; double acc_noise_sigma = 0.000880; //　m/(s^2) double acc_bias_sigma = 0.000021;
