Feature/update pre commit

[TommyMatthews]

Updates pre commit to use the latest version of ruff and not black.

Had to add a few things to ignore in ruff.toml, generally I used the project template approach for guidance. The two I'm least sure about were the following (done in order to avoid having to manually edit loads of files):

• E501 line length - apparently 88 is the line length preferred by black but with this set it was suggesting editing a lot of lines in supposedly black approved code
• E721 - forces isinstance() over is type() etc

Fixed ruff's complaint about using int | float instead of just float. Done in a specific revert so easy to revert if we don't like this.

on the E501 override - did you take a look at what changes the formatter would make here? Keeping line length down is one of the features of Black I would quite like to preserve here. So long as code functionality is not affected (which it shouldn't be!) I would be in favour of just making the automatic changes suggested by the formatter now.

@davidhopkinson26 there are about 800 lines flagged by this error, but they are left unchanged by the formatting and the linting - I don't think that this functionality has made it into ruff formatting yet. Perhaps we leave this PR out until it's in?

@TommyMatthews I think another option might be to set the line length parameter in ruff.toml to a slightly higher number to accommodate the code as is. docs. Would suggest trying 88 first as I'm guessing ruff might be set lower by default to be getting this issue.
