TCN: CSV Dive file generation, data generation with correct step GT, re-training

[periakiva]

1. CSV Dive file generation: done in the PTG Data generation stage. current method requires a Dive CSV format for the GT
2. using action GT labels was mapped to step GT with hard-coded logic; we now simply use the step GT
3. retraining of all tasks with correct GT, with new config files

I've tested this update to the submodule within angel_system master and performance on an existing bag did not change. 👍
