Update dependencies. Fix clippy lints.

The ERFA C library is no longer needed, so all mentions of it are removed.

rubbl_casatables now uses thiserror instead of failure, meaning we no longer
need to unwrap its errors. Also update how DUT1 info can be accessed from a MS.

hifitime methods replaced a heap of "as_" and "in_" methods with "to_" (my
fault!). Also use its new Duration::from_seconds (and similar) methods.

atty is no longer considered sound, so use is_terminal instead. (Unfortunately
atty is still being used by other dependencies, but this change is still worth
doing.)

Stop importing std::ops::{Deref, DerefMut} for things that can be dereferenced
directly (e.g. `beam.deref()` is now `&*beam`, when `beam` is a `Box<dyn
Beam>`).

 - More CUDA benchmarks for the modelling code.
 
 ### Fixed
+- When raw MWA data is missing gpubox files in what is otherwise a contiguous
+  spectral window, it is no longer treated as a "picket fence" situation.
 - Flux densities were not being correctly estimated for curved-power-law
   components with GPU code.
