This commit does:
- Downgrade to uniffi 0.25.0 because of Go bindings
- Fix compile error. upgrade macos to 10_15
- fix Swift build path for RustFramework
- Add cdylib type for [lib] so that GoLang can build bindings from
- proc_macros
- Generate Go Bindings
-
- changes `ParticipantIdentifier` to be represented as a hex
-   string instead of bytes, because GoLang can use Bytes as a key
-   for maps [see](NordSecurity/uniffi-bindgen-go#52)
- Go module + tests
- Add GoLang to README and build scripts
- Github action to build and test bindings
- Build and test swift package locally
- Fix target replacement
- remove pipefail because github action does not like it
- fix swift.yml
- fix build go bindings script
- fix go bindings generation
