Cli options "--image" and "--gdb"

[BrianPugh]

PR for issue #114

Adds CLI options to allows specification of the UF2 image being loaded as well as whether or not to start the GDB server. All default functionality is the same as before. Example usage:

npm run start:micropython -- --gdb --image=circuitpython.uf2

This is my first time using javascript/typescript, so I would love feedback on if anything in this PR isn't idiomatic.

EDIT: updated title/example command to match changing --no_gdb -> --gdb.

Thanks for making the changes!

Can you please also format the code with prettier and make sure eslint is happy?

npx prettier --write filename should do the trick

There's a pre-commit hook that should do this automatically, but it didn't work in your case for some reason

linted

Also, I don't see a .pre-commit-config.yaml in this repo.

Thanks! Then I think the only things we are missing is:

Please also document the new options in the project's README (so other users can find out about them)
