intl-getcanocicallocales is probably not a good idea

Referring to:

• Validating initialLocale before using it #217

1. The package is huge, relatively speaking.

   
   (Bundlephobia)

   I was not sure whether that would be representative, e.g. maybe there was some unused code that would not end up in the final bundle, but putting the new svelte-i18n version in a test project, that does not look too good.

   root/_app/immutable/nodes/6.01fdf54a.js/E:/dev/sveltekit-test/node_modules/@formatjs/intl-getcanonicallocales
   Rendered: 89.91KB (0.54%)
   Gzip: 23.79KB
   Brotli: 17.64KB

   Rendered is a byte size of individual file after transformations and treeshake.
   Gzip and Brotli is a byte size of individual file after individual transformations,
   treeshake and compression.

2. It breaks usage in the REPL.

   • 3.7.0
   • 3.7.1

3. It does not seem to actually solve whatever is the root issue.
   I noted in the associated issue that the issue can happen even with ostensibly valid locales. When testing the new version in my application, interpolation is still broken, but works with v.3.2.0.

Hey @brunnerh, you're right. I will take a better look at this

Let's continue on #209
