Improve fingerprint-generator path resolution for fingerprint-network-definition.zip

[chrbala]

Describe the feature
Right now, the system requires a specific path to fingerprint-network-definition.zip.

It would be great if there could have a more ergonomic way of being provided. Options:

Provide via env variable

One simple option could be to update the line to:

path: process.env.FINGERPRINT_NETWORK_DEFINITION_PATH || `${__dirname}/data_files/fingerprint-network-definition.zip`

Thread through the system

The path could also be threaded through the system, from the constructor up through newInjectedPage in fingerprint-injector.

Inline the data

Finally, the artifact could be inlined into a built artifact. This would be the easiest for consumers, but could make other environments more complex, and may be slower than loading as a separate file.

Motivation
I am trying to use the fingerprint-generator package in an environment which bundles its JS files, which munges the paths and doesn't include the fingerprint-network-definition.zip file by default.

Constraints
Inline the zip file into the bundle and/or allow specification of the zip file path (requiring the user to copy the file into the right place).

The system should also log where it checked for the zip file if it's unable to find the file.

Same goes for the utils file in fingerprint-injector.

Hello, and thank you for your interest in this project!

The envvar solution seems logical. Would you be up to creating a PR?

Cheers!

Thanks for the quick response @barjin—I've made a PR at #520. I already shipped an alternative in my code with patch-package, but it'll be nice to have a properly supported solution :)
