v2.0.0 Release Notes

New Features

DownloadStaticFile Function
- Added a new method DownloadStaticFile to the Tools struct for downloading files. This method sets the Content-Disposition header to "attachment" to force file download rather than display in the browser. Additionally, it allows for a specified display name.
```
func (t *Tools) DownloadStaticFile(w http.ResponseWriter, r *http.Request, pathName, displayName string) {
    w.Header().Set("Content-Disposition", fmt.Sprintf("attachment; filename=\"%s\"", displayName))
    http.ServeFile(w, r, pathName)
}
```
JSONResponse Struct
- Introduced the JSONResponse struct for a standardized format of JSON responses. It includes fields for:
  - Error (a boolean indicating if there is an error)
  - Message (a string for the message)
  - Data (an optional field for additional data)
```
type JSONResponse struct {
    Error   bool        `json:"error"`
    Message string      `json:"message"`
    Data    interface{} `json:"data,omitempty"`
}
```
