fix(isDataURI): fix dataURI mediaType format
fix(isDataURI): fix dataURI mediaType format

The readAsDataURL method [MDN](https://developer.mozilla.org/en-US/docs/Web/API/FileReader/readAsDataURL) generates a dot mediaType for some file formats (.docx - application/vnd.openxmlformats-officedocument.wordprocessingml.document, . xlsx - application/vnd.openxmlformats-officedocument.spreadsheetml.sheet).
I extended the mediaType validation pattern to be compatible with readAsDataURL.
