detect if a file extension is text/ binary or file is text/ binary. uses the file.ext and the file.ext.exttwo detection pattern structure

• detect file extensions
• detect if one of many possible script injection files
• check your file extension using provided string or array
• check if file is part of list of extension
• detect file extension is text
• detect file extension is binary
• detect if file is text
• detect if file is binary
