Dependency on specific npm Version

[BenediktAllendorf]

Hey everyone,

We're trying to use this package in our project, but the installation fails:

/app $ npm install @mapbox/assembly
npm ERR! code EBADENGINE
npm ERR! engine Unsupported engine
npm ERR! engine Not compatible with your version of node/npm: @mapbox/assembly@1.5.1
npm ERR! notsup Not compatible with your version of node/npm: @mapbox/assembly@1.5.1
npm ERR! notsup Required: {"node":">=14","npm":"^6.0.0"}
npm ERR! notsup Actual:   {"npm":"9.4.0","node":"v19.6.0"}

Is there a reason for limiting the usable npm version in such a way?
(Even if that is necessary for development, it might not be for projects using this library?)
