Add run command to CLI

[JulianGCalderon]

• Adds run command to CLI
  • if no path is sent, it runs the current project's main (like build, but also running the binary)
  • if a path is sent, it builds and runs that concrete file in single file mode.
• Adds an example project, can be used to test the run command in project mode.

Example usage:

cargo run -- run examples/fib_if.con
# or
concrete run examples/fib_if.con

tip: to install the binary, run:

cargo install --path crates/concrete
