Gsheets-plaid

This release streamlines the web server UI a little bit.
* Instead of being able to track sandbox, development, and production Plaid credentials, it only tracks one of them
* Hyperlinks are converted into buttons
* Buttons are disabled when they should be

This release fixes an issue in 0.4.0 where the HTML templates and JavaScript static files weren't included in the distribution binaries.

Removed `.env` references and updated README to fix issue described in 12.

Also added a button to remove a Plaid item in the web server.

Releasing v0.2.0 with a brand new web server for managing credentials. See 10 for more details.

This release fixes a bug where the port number was hardcoded in some places, so changing it in the `.env` would break the project. Now the port numbers all refer to the environment variable 😌

Unfortunately, I had to reorder a couple variables in the `.env` template to get this to work, so you'll have to either dig in to the `.env` file yourself or uninstall and then reinstall the project. As pointed out in 3, because the tokens are stored in plain text in the install directory, pip won't delete these files, so you'll have to `rm -rf /path/to/lib/python3.10/site-packages/gsheets-plaid/` yourself :confused:

I'm planning on a future release where we migrate away from all this file nonsense.

Fixed the following bugs:
* The token file wasn't created automatically
* `--env` flag wasn't working for the `link` command
