Installing an NPM package on Bangle.js 2?

For a project I would like to run a discrete wavelets tranform on my Bangle.js 2 watch.

Because of that, I am wondering if it is possible to install an existing npm package (namely https://www.npmjs.com/package/discrete-wavelets ) in Espruino, to make its functionality available within my JS project.

Concrete questions I am pondering about:

• Is it possible at all to install an npm package in Espruino?
  
• Which npm package size is okay for the Bangle.js 2 watch - especially when it comes to memory?
  
• Can the code of the npm package be stored in and run from the Bangle.js 2 flash memory, instead of RAM? How would I achieve this (or prevent that it moves to RAM for execution)?
  
• Could I precompile the npm JS code (to C, to binary), to make it run faster?
  
  

Thanks in advance for any help and hints! :-)
