fix: Change stroke_alpha range from 0-100 to 0-255

Updates the `stroke_alpha` attribute to use the standard Android alpha range of 0-255 instead of 0-100.

- Changes the default value of `stroke_alpha` to 255 in `ShadowLayout`.
- Updates the README to reflect the new range (0-255) and the new default value (255) for `stroke_alpha`.
