Add an Option to Outline to the Local Player Model

[NicBelanger23]

Love this mod and figured I'd try to address a small gripe I have with it.

I often find that when flying around I can lose where my player is, and need to exit freecam to regain my bearings.

• Added a visual setting that enables a glowing outline on the local player while freecamming. I'd love to hear what you think!

This is my first experience with Fabric API and modding Minecraft in general, so please point out anything outside of best practice. Thanks!

Sorry for the long delay responding to this PR.

For context, we've been busy doing major internal refactors including changing the i18n translation file format, refactoring the config system into a separate model and interface, and porting from multiple MC-version branches to a single multi-version branch (using stonecutter).

The feature itself sounds useful and the approach used seems simple enough to maintain.

Are you willing to rebase your PR on the latest main revision and update it to be compatible with supported mc versions (using stonecutter directives)?
