Graham McIntire 00a8f996f4
Add Gleam language integration to Elixir project
- Rename Gleam module from encoding_simple to encoding
- Move Gleam files from src/aprs/ to src/aprsme/ to match project namespace
- Create custom Mix task for Gleam compilation (lib/mix/tasks/gleam_compile.ex)
- Update EncodingUtils to wrap Gleam implementation instead of pure Elixir
- Add Gleam dependencies to mix.exs and configure build paths
- Update Mix aliases to include Gleam compilation in test and compile tasks
- Add Gleam support to GitHub Actions CI workflow with caching
- Add GLEAM_INTEGRATION.md documentation
- All 357 tests passing with Gleam integration
