New options for datasette install: --pre, -e, -r and others

[simonw]

https://llm.datasette.io/en/stable/help.html#llm-install-help has a few more options I could borrow:

Usage: llm install [OPTIONS] [PACKAGES]...

  Install packages from PyPI into the same environment as LLM

Options:
  -U, --upgrade        Upgrade packages to latest version
  -e, --editable TEXT  Install a project in editable mode from this path
  --force-reinstall    Reinstall all packages even if they are already up-to-
                       date
  --no-cache-dir       Disable the cache
  --help               Show this message and exit.

I can't remember why I added --no-cache-dir to that command.

Oh, here's why:

• install --no-cache-dir and --force-reinstall options llm#146

They were useful to get a fix for a bug in a compiled C package. Since Datasette might need those too I'll add them here as well.

Copying from pip install --help:

  --force-reinstall           Reinstall all packages even if they are already
                              up-to-date.
  --pre                       Include pre-release and development versions. By
                              default, pip only finds stable versions.
  -e, --editable <path/url>   Install a project in editable mode (i.e.
                              setuptools "develop mode") from a local project
                              path or a VCS url.
  --no-cache-dir              Disable the cache.
  --force-reinstall           Reinstall all packages even if they are already
                              up-to-date.

I'm going to add -r/--requirements too, because it's useful for e.g. datasette install -r plugins.txt.
