Fix/build broken

[0xclem]

Vercel builds are currently broken because next-optimized-images hasn't been updated for a while and uses an old version of sharp which doesn't seem to be compatible with latest node & npm version.

Here is the fix:

• Removed next-optimized-images from the repo
• Forked and modified optimized-images-loader (which is used by the library above to load SVGs via webpack) to be using a newer version of sharp which is compatible with latest node & npm.
• Added @svgr/core to package.json (needed to make it work without next-optimized-images)
• Added the forked version of optimized-images-loader (see here) to package.json
• Added react-optimized-image (which was included in the initial library we removed) to package.json
• Rewrote the Webpack logic to be using the forked version of optimized-images-loader
