fix build issue and format repo

[lromor]

Also removed the brew unlink jpeg as it was generating:

Disable this behaviour by setting HOMEBREW_NO_INSTALL_CLEANUP.
Hide these hints with HOMEBREW_NO_ENV_HINTS (see `man brew`).
Error: No such keg: /usr/local/Cellar/jpeg
Error: Process completed with exit code 1.

I suspect now the image doesn't have any jpeg keg installed by default, so there's nothing to unlink and replace with turbojpeg, but this is just an assumption.

Please always have one PR per thing fixed, it is otherwise hard to merge (one for formatting, one for CI fix).

I've fixed now upstream the questionable choice of the clang-format to put short blocks into one line, so formatting should now look better.

Closing this, as both the macos and QOI problems got fixed.
