KTX2Loader: Update ktx-parse dependency to v0.7.1

Description

Update ktx-parse dependency from v0.3.1 to v0.7.1 (donmccurdy/KTX-Parse@v0.3.1...v0.7.1) to contain the fix in donmccurdy/KTX-Parse#148.

I couldn't find some good instructions about how to update this compressed module so I did this PR by guessing. Please tell me if some of the processes are wrong.

The steps I took:

1. Clone https://github.com/donmccurdy/KTX-Parse
2. Check out the release tag: git fetch --all && git checkout v0.7.1
3. Remove --no-compress in package.json
4. Run yarn && yarn dist
5. Copy and paste from dist/ktx-parse.esm.js to examples/jsm/libs/ktx-parse.module.js
6. Remove //# sourceMappingURL=ktx-parse.esm.js.map

The steps listed do sound correct, but I'm away from my computer for a couple weeks and unable to test in the meantime. If others have tested and this works, feel free to merge!

Alternatively the ESM build from npm can be used, after removing the sourcemap line. Published builds of ktx-parse are not minified.
