deps: bump encoding_rs to 0.8.16

This brings in an updated `encoding_rs` crate that uses `packed_simd`,
which compiles on the latest nightly. Compilation times do appear to be
impacted significantly though.

Fixes #1175 (again)

 * The `avx-accel` feature of ripgrep has been removed since it is no longer
   necessary. All uses of AVX in ripgrep are now enabled automatically via
   runtime CPU feature detection. The `simd-accel` feature does remain
-  available, however, it is broken in the latest nightly release of Rust.
