feat: Add fetchOptions to install

do we maybe need to set a default value for the fetchOptions parameter so you don't have to pass null explicitly? or.. like does javascript do that automatically. i'm thinking like install(fetchOptions = null) maybe? i think it might just be undefined though if you don't pass it. just want to make sure it's backwards compatible

JS automatically assigns undefined for parameters that are not passed and the spread operator (...) will return nothing when it tries to spread undefined or null. So calling install() is the same as calling install(undefined). If we want to have a safe default we could default to an empty object like install(fetchOptions = {})

ok, i think it's fine to leave as is then :)
