cc2874c9a9 Add scalbnf16, scalbnf128, ldexpf16, and ldexpf128 
Use the generic `scalbn` to provide `f16` and `f128` versions, which
also work for `ldexp`.

This involves a new algorithm for `f16` because the default does not
converge fast enough with a limited number of rounds.

62f0fd40d1 Use az exported from Rug 
Since Rug 1.27.0, `az` is reexported. This means we no longer need to
track it as a separate dependency.

71200bc3ce Add fmodf128 
This function is significantly slower than all others so includes an
override in `EXTREMELY_SLOW_TESTS`. Without it, PR CI takes ~1hour and
the extensive tests in CI take ~1day.

dfa694a8e4 Add a utility crate for quick evaluation 
Introduce a simple binary that can run arbitrary input against any of
the available implementations (musl, MPFR, our libm). This provides an
easy way to check results, or run specific cases against a debugger.

Examples:

    $ cargo run -p util -- eval libm pow 1.6 2.4
    3.089498284311124
    $ cargo run -p util -- eval mpfr pow 1.6 2.4
    3.089498284311124
    $ cargo run -p util -- eval musl tgamma 1.2344597839132
    0.9097442657960874
    $ cargo run -p util -- eval mpfr tgamma 1.2344597839132
    0.9097442657960874
    $ cargo run -p util -- eval libm tgamma 1.2344597839132
    0.9097442657960871
    $ cargo run -p util -- eval musl sincos 3.1415926535
