Summary:
Applies new import merging and sorting from µsort v1.0.
When merging imports, µsort will make a best-effort to move associated
comments to match merged elements, but there are known limitations due to
the diynamic nature of Python and developer tooling. These changes should
not produce any dangerous runtime changes, but may require touch-ups to
satisfy linters and other tooling.
Note that µsort uses case-insensitive, lexicographical sorting, which
results in a different ordering compared to isort. This provides a more
consistent sorting order, matching the case-insensitive order used when
sorting import statements by module name, and ensures that "frog", "FROG",
and "Frog" always sort next to each other.
For details on µsort's sorting and merging semantics, see the user guide:

TL;DR In come cases:
1) user imports `dill`, which mutates `_Pickler.dispatch`,
2) user imports lib that imports `torch.package`
3) `PackagePickler.dispatch = _Pickler.dispatch.copy()` makes a copy of the mutated table
4) user calls `dill.extend(use_dill=False)` to reset `_Pickler.dispatch`, expecting everything to be okay
5) `PackagePickler` is used to pickle something like `ModuleDict`. `PackagePickler.dispatch` has stale entries to dill pickle functions like `save_module_dict`, which sometimes hard-code calls to `StockPickler.save_global`, which is unaware of torch.package module prefixes.
6) Exception is raised, e.g. `Got unhandled exception Can't pickle <class '<torch_package_2>.caffe2.mylib'>: it's not found as <class '<torch_package_2>.caffe2.mylib'>`

This makes our API symmetric--now we have an `Importer` aware Pickler
and Unpickler implementation that have similar interfaces.

I am planning the custom pickler and unpicklers that we use as
semi-public interfaces for `torch.rpc` to consume. Some prefatory
movements here.
