Uproot

jpivarski cleanly ensured all `Interpretation.awkward_form` signatures have been reverted (even `AsJagged`): PR 627.

jpivarski applied this fix: https://github.com/scikit-hep/uproot5/pull/618#discussion_r903623799.

First Uproot 4 release from the bug-fix branch.

jpivarski added a TMatrixTSym model (long stalled PR): 484.

aryan26roy restored the argument list of `Interpretation.awkward_form`, a public function: PR 618.

kkothari2001 implemented `uproot.dask` (for `library="np"` only), a new function to provide Uproot data as Dask arrays: PRs 578, 603. Added another new function, `uproot.num_entries`, for getting the number of TTree entries from a set of files with minimal reading: PR 609.

jpivarski removed tests that rely on a ROOT TStreamerInfo behavior: PR 612. Changed `awkward_form` arguments to `(self, file, context)` so that new pseudo-arguments can be passed through the `context` without another major code change: PR 611. This is to prepare for aryan26roy's AwkwardForth implementation of `AsObjects` interpretations (see 610, WIP targeting Uproot 5).

**Note:** this is the last Uproot 4 release before the repo branches into `main` (for version 5) and `main-v4` (for bug-fixes in Uproot 4, starting with 4.3.0). Uproot 5 will incorporate Awkward version 2, as described in the [Awkward road map](https://github.com/scikit-hep/awkward/wiki#grand-view-and-history), but it will have minimal interface changes relative to Uproot 4 (mostly just `uproot.lazy` → `uproot.dask`).

jpivarski fixed the use of Unicode names for objects in ROOT files: PR 577. Made `flow=True` mean the same thing for Uproot histograms as hist: PR 582. Added an interpretation for `ROOT::VecOps::RVec`: PR 593. Replaced an error message in HTTPSource with a fallback to the non-multipart-GET case: PR 594. Put an upper limit on the time KeyInFileError takes to print itself: PR 595.

jpivarski fixed 572: PR 573.
