feat: add initial support for delta updates (#308)

* pyproject: add optional dependencies

* requirements: add optional dependencies

* feat: add rust library

- Will currently be used for the security part of the delta update system.

* Makefile: add build target for rust module

* umu_util: add function to create anon files

* umu_consts: add new install path

- Private directory for compatibility tools that are not runtime related, which will be supported for delta updates

* umu_run: remove UMU-Latest link if exists

* umu_run: support new codenames

* feat: add delta patcher

* umu_proton: delete function remove old builds

* umu_proton: don't create UMU-Latest link

* umu_proton: add function to fetch patch

* umu_proton: support finding delta builds

* umu_proton: remove redundant install_proton

* umu_proton: refactor install for delta builds

* umu_proton: refactor pre-install steps for delta builds

* umu_proton: add functionality to apply delta updates

* umu_test: update tests

* umu_test: add initial delta update tests

* deb: update deb package

* rpm: add optional dependencies

* snap: add optional dependencies

* nix: update flake

* ci: add new dependencies to workflows

* README: update description for nix

Co-authored-by: beh_10257 <[email protected]>

* .gitignore: update ignore

* docs: update description for PROTONPATH

* pyproject: fix parsing error

* umu_proton: fix log statement

- Wrong Proton build was printed to stderr

* umu_proton: update style

* umu_proton: fetch patch from endpoint

* umu_proton: implement _fetch_patch

* umu_proton: add GE-Latest codename to set

* umu_proton: fix not waiting for future

* umu_proton: fix mypy lint

- Ignore the type. There's an open issue upstream for this, and we can refactor for readability later if desired

* umu_proton: fix mypy lint

* ci: don't use latest runner

- For now, run the e2e tests on Ubuntu 22.04 because the tests are failing due to not using the bwrap apparmor profile:

pressure-vessel-wrap[2993]: E: Child process exited with code 1: bwrap: setting up uid map: Permission denied

Fix this later in a separate commit or pull request
