Mechanism for causing datasette publish and datasette package to install one or more additional plugins using pip install - refs #14

[simonw]

Demo:

datasette publish now sortable.db --install datasette-plugin-demos --branch=master

Produced this deployment, with both the random_integer() function and the static file from https://github.com/simonw/datasette-plugin-demos/tree/0.2

https://datasette-issue-223.now.sh/-/static-plugins/datasette_plugin_demos/plugin.js

Tested on Heroku as well.

And tested datasette package - this time exercising the ability to pass more than one --install option:

$ datasette package sortable.db --branch=master --install requests --install datasette-plugin-demos
