Use proper libm power method for f64s

Browse source 
For some reason when attempting to raise floats to powers in
scoring we'd converted our `f64`s to `f32`s, called `libm::powf`
(on no-std targets), then converted the result back to an `f64`.
`libm::pow`, however, exists and raises `f64`s to a power natively.

Here we correct this, using the proper `f64`-native `pow`.

While I doubt its related, I went to look if we have any conversion
in LDK itself in response to
https://github.com/lightningdevkit/ldk-node/issues/483 (where
Android binaries failed to load due to a missing `__extenddftf2`.
