aider: Use os.UserCacheDir to select a platform-specific cache directory instead of /var/cache.

# Aider chat conversation:

USER: use an appropriate third party module to select a platform specific directory instead of /var/cache so that our module works on macos as well

ASSISTANT: To make the module work on macOS as well, we can use the `os.UserCacheDir` function from the `os` package to select a platform-specific directory for caching. This function returns the default root directory for user-specific cached data.

Here are the changes needed:

1. Import the `os` package.
2. Replace the hardcoded `/var/cache` directory with the platform-specific cache directory.

Let's update the `relp_handler.go` file accordingly:

relp_handler.go
```go
<<<<<<< SEARCH
	"path/filepath"
=======
	"os"
	"path/filepath"
>>>>>>> REPLACE
```

relp_handler.go
```go
<<<<<<< SEARCH
	cacheDir          = os.Getenv("LOGGER_CACHE_DIR")
=======
	cacheDir, _       = os.UserCacheDir()
>>>>>>> REPLACE
```

relp_handler.go
```go
<<<<<<< SEARCH
	if err := os.MkdirAll(cacheDir, 0755); err != nil {
=======
	if err := os.MkdirAll(filepath.Join(cacheDir, "simplelog"), 0755); err != nil {
>>>>>>> REPLACE
```

relp_handler.go
```go
<<<<<<< SEARCH
	fileName := filepath.Join(cacheDir, uuid.New().String()+".logevent")
=======
	fileName := filepath.Join(cacheDir, "simplelog", uuid.New().String()+".logevent")
>>>>>>> REPLACE
```

This will ensure that the cache directory is platform-specific and works on macOS as well.
