docs(license): split the data carve-out into NOTICE

The carve-out was 180 words appended to LICENSE, which pushes the file below
the similarity threshold licence detectors match against — a repository whose
licence reads "other" is less inviting to a forker than one that reads MIT,
and the carve-out was never part of MIT's text anyway.

LICENSE is verbatim MIT again, plus three lines binding NOTICE into the terms
so the carve-out travels with any copy rather than being optional reading.
NOTICE carries the substance. README points at both.
