This PR builds the basic theory of packed floats, along with a lot
of proof automation, to enable us to prove that 'toExtRat' is injective
on packed floats.
The subsequent PR will prove that 'normalize' is idempotent on unpacked floats,
and does not change the 'toExtRat'. These form the cornerestones
of the interpretation, and will build sufficient proof machinery to
continue with rounding.
