deps: bump encoding_rs to 0.8.16

Browse Source 
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)

If you have a Rust nightly compiler and a recent Intel CPU, then you can enable
additional optional SIMD acceleration like so:
**WARNING**: Building with the `simd-accel` feature on the latest Rust nightly
does not work because the [`encoding_rs`](https://crates.io/crates/encoding_rs)
crate hasn't yet migrated to the new SIMD infrastructure, and the old SIMD
infrastructure no longer works on the latest nightly version of Rust.

The `simd-accel` feature enables SIMD support in certain ripgrep dependencies
(responsible for transcoding). They are not necessary to get SIMD optimizations
for search; those are enabled automatically. Hopefully, some day, the
`simd-accel` feature will similarly become unnecessary.

enabling this option can increase compilation times dramatically.
