v1.0.0

We officially release the 1.0.0 version of the library. In this version, we have made the following changes:

1. ✨ NEW!: We add the threshold parameter to control the proportion of face areas (Defaults to 0.3).
   • In previous versions, the library could incorrectly identify non-face areas as faces, such as shirts, collars, necks, etc.
     In order to improve its accuracy, the new version will further calculate the proportion of skin in the recognized area
     after recognizing the facial area. If it is less than the threshold value, the recognition area will be ignored.
     (While it's still not perfect, it's an improvement over what it was before.)
2. ✨ NEW!: Now, we will back up the previous results if it already exists.
   The backup file will be named as result_bak_<current_timestamp>.csv.
3. 🐛 FIX!: We fix the bug that the image_type option does not work in the previous version. Thanks @wrightmk.
4. 🐛 FIX!: We fix the bug that the library will create an empty log folder when checking the help information by running stone -h.
