New command: spacetime dev (#3469)

# Description of Changes

This PR implements a new command for the CLI: `spacetime dev`. If run
from outside of a project directory, it will call `init` in interactive
mode to allow user to create a project. If run from a project directory,
it will ask for a module to conect to and it will:

* subscribe to logs
* observe files in the `spacetimedb` directory and automatically publish
to SpacetimeDB

One caveat is that instead of reusing the `logs` code I did some
repetition cause currently the logs code acquires a lock that lives
through await points. It is fixable, but due to limited time I decided
to go with a bit of code duplication. It shouldn't be very hard to fix
later, though.
