Unable to install/use this package

[ashar340]

I ran into this to consider using keys as any dataType but not limited to comparable.

I tried moving the source code (elm modules) for Hash.Dict and it's dependent modules to my local directory of the project but hit this here in src/Hash/FNV.elm

MODULE NOT FOUND - You are trying to import a `Elm.Kernel.FNV` module:

3| import Elm.Kernel.FNV
          #^^^^^^^^^^^^^^#
I checked the "dependencies" and "source-directories" listed in your elm.json,
but I cannot find it! Maybe it is a typo for one of these names?

This import is causing the issue:

import Elm.Kernel.FNV
           ^^^^^^^^^^^^

My understanding is that it is the compiled code (.js file) and not an elm module which can be consumed directly and I am unable to consume this package locally.

I considered using this but it's unsupported for v0.19 due to certain reasons:
#gdotdesign/elm-github-install#62

Is there a way to install this module locally it being not available through package manager for installation.
