weigit: Fixed file tracking with metadata. Changes in sha1_store for better encapsulation. Docstrings. (#1013)

* [Feat] Fixed file tracking with metadata. Change in sha1_store for better encapsulation. Tests.

1. Adds metadata creation per added file and independently tracks version of each separate file added. That is, now creates separate metadata files
   for each file to be tracked.
2. Changes in reference tracking to accomodate the change in 1.
3. Somes changes in SHA1_store for better encapsulation.
4. Modified the tests to reflect above.

* [Feat]
1. Added docstrings to the classes.
2. Added a recursively search for the weigit repo upto root.
3. Some refactor of the codes.

* [Feat][Refactor] repo and sha1_store add modification and separation. Modification in reference tracking

1. Separation of add functionalities of repo.add and sha1_store.add.
2. Updated the reference tracking.
3. New tests and code refactor

* [Fix] Sha1_store fix overlap in first two characters of sha1 hash.

[FSDP] ssd_offload fixing backward path (grad_fn) for SsdFlatParameter and SsdFlatParameterView (#974)

* [FSDP] fixing backward path for SsdFlatParameter and SsdFlatParameterView when overriding .data

* Get ssd_offload unit tests passing

Improvements to ssd_offload to support pickling/unpickling SsdTensorHandle (and derived classes) (#964)

Verified that FSDP wrapped models using ssd_offload checkpoint save and restore correctly

This is no longer needed since isort's version is 5.10

Also fix black version to 22.3.0 to fix issue with click
dependency.

Update files that now fail with new version of black {a = 2 ** 4} ->
{a = 2**4}

* add an ignore file

* [fix] FSDP: handle the lazy_init better

- when state_dict and load_state_dict is called, let'em not change
  the lazy_init state.

* longer timeout

* Revert "longer timeout"
