how to adjust the iteration number

[TomZhongJie]

The iteration number of each scene in UTMM_Dataset is fixed, how do I adjust the iteration number? Changing the iteration in UTMM.yml will not help, but also cause an error when running

To change the number of optimization iterations for tracking/mapping, look at tracking/iters or mapping/iters.

iteration is for loading a checkpoint, and requires that an existing saved output already exists in the output directory.
