GitHub reports no license because LICENSE.txt lacks a BSD-2-Clause identifier

GitHub's API currently returns license=NOASSERTION for this repo even though LICENSE.txt is two-clause BSD and README/CONTRIBUTING already say that.

LICENSE.txt starts with "Copyright (c) 2015- John Kerl" plus the two redistribution bullets and the as-is disclaimer. There is no "BSD 2-Clause License" title and no SPDX-License-Identifier: BSD-2-Clause line, which is what licensee uses to classify BSD-2-Clause.

Ask: add a title line and/or an SPDX identifier to LICENSE.txt (text unchanged otherwise). I am not asking to change the license terms.

I can send that one-file PR if you want it. No need if you prefer GitHub to stay unclassified.
