muhammara package breaks mac dev by default

[mikemitchel]

MuhammaraJS (the drop-in replacement for hummusjs) is processor/architecture specific so when trying to run 'npm run dev' on a mac, it gives this error:

/a2j/dat/node_modules/muhammara/binding/muhammara.node' (mach-o file, but is an incompatible architecture (have 'x86_64', need 'arm64'))

need some kind of architecture auto detect, or a wiki update on how to change it easily.

A quick but likely insecure workaround is to uninstall MuhammaraJS and re-install HummusJS and fix the require statements in pdf.js and assemble-utils.js.

This may be a versioning issue that could be resolved by downgrading the version of muhammara as a less insecure alternative to the Hummus fix.
