Version 2.0.0rc1

[jpivarski]

This is the first (pre) release of Awkward 2, after main and main-v1 have diverged (considerably). There is no awkward._v2 submodule in this release. Any instances of

import awkward._v2 as ak

need to be changed to

import awkward as ak

to use this release. Also, there is no guarantee that Awkward 1 code will work in this release; it is a (slightly) backward incompatible major release, but not final until 2.0.0 (no "rc" number).
