Add simplified Docker Compose support for tests

[kjsanger]

Remove the requirement to set up iRODS client wrappers before tests will run.

Support both plain CLI and IDEs.

GitHub CI is not using this to run tests, although potentially it could. That would need additional parameters for Docker to select the correct iRODS server and clients, which is currently hard-coded into the Dockerfile.dev

I'm hoping that this will simplify things, but I'd lke some feedback on whether that's actually the case. It works for me and I can get rid of the iRODS wrappers and extra client container.

This seems better for me as well, it makes setup less complicated and eliminates the errors that occur because of running the tests on a mac. It did take my mac more than 15 minutes to build the docker image on the first run (70% of which was installing python), but after that it was faster than the old setup (possibly due to those mac induced failures). Perhaps mention that the initial run time will be long in the README?

I ran it on my vm with ubuntu and I got 89 passed tests and 2 skipped:

- s It: tests/test_irods.py::TestDataObject::test_verify_checksum_good - Can have its checksum verified as good
- s It: tests/test_irods.py::TestDataObject::test_verify_checksum_bad - Can have its checksum verified as bad

While installing python 3.12.3, this error appeared but did not affect the build or tests:

This is a very useful feature for testing... probably every repository should have a containerised env for tests

The lines like this are warnings which occur because I have not installed some optional development apt packages. We could add these later to make the warnings go away.
