Niels Lohmann 7e3dfc70c6 Compare dump()s instead of json values in the BJData fuzzer's round-trip check ...

The value-stability assertion added to fix the earlier OSS-Fuzz crash
(json::from_bjdata(to_bjdata(j2)) == j2) itself broke on a NaN payload:
IEEE 754 NaN is never equal to itself, so operator== reports two
structurally-identical trees containing a non-finite double as
different -- not a round-trip bug, just NaN's ordinary
non-reflexivity. dump() serializes any non-finite double the same
deterministic way (as JSON null, since JSON cannot represent NaN or
Infinity), so comparing dumps is stable under exactly the values that
break operator==.

Verified against both the original OSS-Fuzz crash input and the new
one (0x68 0x68 0x7c, which decodes to a NaN), plus a local 2.5M-case
random-input sweep with no failures.
