Using file signatures attempt to determine the mime-type of a buffer
npm install binary-typeA simple package that provides the ability to check if a buffer matches
a specific mimetype, and secondly the ability to guess a mimetype given
a buffer.
Return true if the supplied buffer has a binary file signature that
matches what is expected for the specified mimetype.
Run the supplied buffer through the various known mimetypes to attempt
to determine it's mimetype (returned as a string value if found).
__NOTE:__ Only a few file signatures have been implemented at this stage,
but feel free to issue a pull request if you require additional types. A
good resource of binary file signatures can be found at the following url:
