Code for TSMixup dataset creation

[ben-jy]

Hi !
As I am trying to reproduce pretraining of Chronos from scratch and experimenting few things, I would like to know if a script/code exist in order to create the tsmixup dataset in arrow format, from scratch ? Maybe a bit of data cleaning is done, etc. ?
Also, it would useful to have documentation and code describing how to convert the hf training corpus datasets to arrow, in order to reproduce pretraining. Maybe I have missed that.

I think they addressed tsmixup code here #213
