If I run monas install --include pkgname, that command will not install the optional dependencies. If that project needs pytest, for example, I will not be able to run tests in that project until I navigate to the project, and run pip install .[test]

Describe the solution you'd like
The existing workflow isn't terrible, but there might be something better.

When you run monas with the --include flag, it is using a fnmatch to match the pattern.
I wonder if we could use a different flag to target a package in the more traditional way, like

monas install --local_pkg pkgname[test]

That command could check against the package name rather than the directory. If it matches a local package exactly (or on a normalized name), then it would install the local dependencies with -e, and then install the specified package with [test] brackets at the end (or whatever option was specified).

Another option would be to add a flag for optional dependencies to install

monas install --include pkgname --optional_dependencies test

and that would similarly add [test] to the install command for the packges that match the --include pattern

Open to thoughts.
