Use latest wasm-opt instead of one in wasm-pack

wasm-pack auto-downloads and runs a fixed version of wasm-opt, but wasm-pack itself hasn't been maintained for a while, and so wasm-opt that comes with it is also severely outdated, leading to all sorts of hidden issues (compiler errors, broken atomics code, etc.) as well as missed optimisations.

This change disable wasm-opt feature of wasm-pack in all Rust codecs and runs the latest wasm-opt manually instead.

+# Squoosh CLI
+
+Squoosh CLI is an _experimental_ way to run all the codecs you know from the [Squoosh] web app on your command line using WebAssembly. The Squoosh CLI uses a worker pool to parallelize processing images. This way you can apply the same codec to many images at once.
+
+Squoosh CLI is currently not the fastest image compression tool in town and doesn’t aim to be. It is, however, fast enough to compress many images sufficiently quick at once.
+
+## Installation
+
+The Squoosh CLI can be used straight from the command line without installing using `npx`:
+
+```
+$ npx @squoosh/cli <options...>
+```
+
+Of course, you can also install the Squoosh CLI:
+
+```
+$ npm i -g @squoosh/cli
+$ squoosh-cli <options...>
+```
+
+## Usage
+
+```
+Usage: squoosh-cli [options] <files...>
+
+Options:
+  -V, --version                                          output the version number
+  -d, --output-dir <dir>                                 Output directory (default: ".")
+  -s, --suffix <suffix>                                  Append suffix to output files (default: "")
+  --max-optimizer-rounds <rounds>                        Maximum number of compressions to use for auto optimizations (default: "6")
+  --optimizer-butteraugli-target <butteraugli distance>  Target Butteraugli distance for auto optimizer (default: "1.4")
+  --resize [config]                                      Resize the image before compressing
+  --quant [config]                                       Reduce the number of colors used (aka. paletting)
+  --rotate [config]                                      Rotate image
+  --mozjpeg [config]                                     Use MozJPEG to generate a .jpg file with the given configuration
+  --webp [config]                                        Use WebP to generate a .webp file with the given configuration
+  --avif [config]                                        Use AVIF to generate a .avif file with the given configuration
+  --jxl [config]                                         Use JPEG-XL to generate a .jxl file with the given configuration
+  --wp2 [config]                                         Use WebP2 to generate a .wp2 file with the given configuration
+  --oxipng [config]                                      Use OxiPNG to generate a .png file with the given configuration
+  -h, --help                                             display help for command
+```
+
+The default values for each `config` option can be found in the [`codecs.js`][codecs.js] file under `defaultEncoderOptions`. Every unspecified value will use the default value specified here. _Better documentation is needed here._
+
+## Auto optimizer
+
+Squoosh CLI has an _experimental_ auto optimizer that compresses an image as much as possible, trying to hit a specific [Butteraugli] target value. The higher the Butteraugli target value, the more artifacts can be introduced.
+
+You can make use of the auto optimizer by using “auto” as the config object.
+
+```
+$ npx @squoosh/cli --wp2 auto test.png
