Introduce support for user-provided extensions
This change introduces support for discovering and executing user-provided extensions to the program. Extensions are useful for allowing users to provide additional functionality on top of the nitrocli proper. Implementation wise we stick to an approach similar to git or cargo subcommands in nature: we search the directories listed in the PATH environment variable for a file that starts with "nitrocli-", followed by the extension name. This file is then executed. It is assumed that the extension recognizes (or at least not prohibits) the following arguments: --nitrocli (providing the path to the nitrocli binary), --model (with the model passed to the main program), and --verbosity (the verbosity level).
