If an explicit cwd is provided, try searching for the module there if it could otherwise not be determined

The current implementation chooses to search for the module in the following order:
1. <`configPath` directory>/node_modules/
2. main file in <`configPath` directory>/package.json

I have a need for the search to continue. Perhaps if these first two searches turn out unsuccessful, these 2 steps could be repeated in the CWD (in place of the `configPath`) if an explicit one was provided. So the process would be to search for the module in the following order:
1. <`configPath` directory>/node_modules/
2. main file in <`configPath` directory>/package.json
3. <provided `cwd`>/node_modules/
4. main file in <provided `cwd`>/package.json
