v2-MT collection

Hi All,

I am trying to use V2 for my purposes but I am faced with below error when importing MTCollection:
`---------------------------------------------------------------------------

@kashkoulimohammad this looks like an xarray error, something in their testing suite is failing. For reference I have version 2022.6.0 running on my machine. Perhaps try installing that version of xarray and see if that fixes the issue. In the meantime, I'll try upgrading my xarray to the newer version and see if I can track down the issue, but that might take some time.

It also looks like you might have an older version of v2, try either pulling or redownloading https://github.com/MTgeophysics/mtpy/tree/v2.
