5.0.0rc1

[jpivarski]

This is the first 5.0 (pre) release!

It should not be considered stable, and it strictly requires Awkward 2.0, so you need to have the latest pre-release of that. This may be reflected in the lazy import of awkward; if not, a subsequent 5.0 pre-release will get that right.

Changes relative to any 4.x release:

@kkothari2001 removed the uproot.lazy function (though a stub remains for the sake of keeping the documentation until 5.0 is actually released): PR #615. Updated the entire codebase from Awkward 1.x to Awkward 2.x: PR #620.

@aryan26roy changed arguments in the awkward_form method: PR #617. (@jpivarski fixed a bug in it: PR #622.) @aryan26roy completed an AwkwardForth-based reader for AsStrings: PR #616. Made the Python code generation in streamers.py more readable: #629. Revised the way that the AwkwardForth code generator would pass through the control flow: PR #636.

@henryiii added dependabot for GitHub Actions: PR #631. Cleaned up flake8: PR #527.

@jpivarski fixed a performance bug, to allow linear-time iteration over TDirectory fields: PR #638 (backported to v4 as well). Set up as close as possible to full-coverage tests for AwkwardForth: #637.
