Thanx Dave!

I'm surprised that the JOSE folks never referred to this.

LD doesn't return exactly the same result as ES6 serialization
for non-normalized numbers but that is probably not a major
issue because then you are pretty on the limit anyway.

4.9E-324 is converted to 5e-324 in ES6 and in LD to 4.940656458412465E-324
