Made values dynamic in pyproject.toml

Fixes issue #134

When trying to install stylist, pip was throwing errors because certain values weren’t listed as “dynamic” in the pyproject.toml file. Adding the values in question to the dynamic setting fixed the issue.

To reproduce the error you can run the following command inside your stylist repo.
pip install .

The error messages were all like so:

According to the spec (see the link below), however, setuptools CANNOT consider this value unless "readme" is listed as "dynamic".

To prevent this problem, you can list "readme" under "dynamic" or alternatively remove the "[project]" table from your file and rely entirely on other means of configuration.

I think the solution is incomplete. "readme" definitely needed to be added because it is specified as dynamic further down. On the other hand "authors" and "keywords" are not specified anywhere in the file.

I think they need to be added, either statically (in which case removed them from the dynamic list) or dynamically.

Yes I think you're right. I tested with just the "readme" value as dynamic and it works, so I've updated the file.

This looks good to go.
