Bug on i686 architecture

[jvymazal]

When running ctest on i686 arch, there is failed test_float8 with cbor_float_get_float8(float_ctrl) == 1.0e+300, on x64_86 arch works as expected.

The implementation relies solely on C doubles to handle these, which should be portable. I suspect it is a precision issue rather than a completely wrong decoding, but nevertheless this is very interesting.
