Firedrake is not installed with requirements

The hardest part of installation is left manually to the user. The presence of a requirements.txt file is misleading if one of the main components is missing.

Firedrake installation is tricky but could be worse. Unless firedrake becomes pip installable. At least the requirements.txt lets the user know what is required and easy to install.

A way forward is to embed torchfire installation into firedrake so one runs firedrake-install --install torchfire as the recommended installation pathway. Then the dependence on firedrake is solved automatically. Thoughts?

I like the idea of embedding torchfire in the firedrake installation process. This reduces the number of steps a user needs to take in order to have a working installation.

It would also be nice to provide a docker container with all the dependencies installed, though I think we should still make it as easy as possible to install torchfire manually.
