Bypass HTTP download to use local binaries

Nobody has claimed this yet.

Some packages do not have binaries for all platforms, like sqlite3. When trying to `npm install` it on arm64 arch, node-pre-gyp fails with a 403 error (node-pre-gyp: 0.17.0, npm 7.1.0, node 14.16.0), which is totally normal.

I could successfully build my own binaries for sqlite3, but the problem is that node-pre-gyp won't use them. When looking at the error stack, I could determine the path of the binaries:
```
npm ERR! node-pre-gyp info check checked for "root/project/server/node_modules/sqlite3/lib/binding/napi-v3-linux-arm64/node_sqlite3.node" (not found)
```
But I did place the node_sqlite3.node file there (also tried with the .tar.gz), it's readable and even 777'd. I don't understand this error... Looks like a bug as the file mentioned is right where it is supposed to be.
Is there any reason why this isn't working, is there something else to do?

So my question is: how can I bypass the binary download and go directly to the unpack phase by providing locally the .node file?

Reproduce the arm64 npm install scenario and inspect the node-pre-gyp download and unpack flow, using the mentioned node_modules/sqlite3/lib/binding/napi-v3-linux-arm64/node_sqlite3.node path as the starting point. Done means establishing whether a locally supplied .node file or archive can bypass HTTP download and documenting or implementing that behavior with a verifiable install path.
