fix(cli): remove sharp dependency

[frankcalise]

Please verify the following:

• [ ] yarn test jest tests pass with new tests, if relevant
• [ ] README.md has been updated with your changes, if relevant

Describe your PR

• This is the start of removing sharp as a dependency to the CLI which has been linked to many issues: #2483, #2518
• Dimensions are now acquired via buffer-image-size as sharp-cli doesn't allow for printing metadata yet (see old PR)
• Existing sharp commands are now applied via sharp-cli

Still Pending

• Come up with a temp file solution since we can't use buffers anymore
• Other ideas to not have to use sharp-cli at all since maybe that will block bun adoption still? (although unsure)
