chore(nodejs): make opean optional, and apache-arrow a peer dep (#1417)

fyi, this should have no breaking changes as npm is opt-out instead of
opt-in when resolving dependencies

all peer and optional dependencies get installed by default, so users
need to manually opt out.

`npm i --omit optional --omit peer`
