Guess if a file is a text file for a vector of filenames or filepaths

Description

This function will guess if a file is a text file for a vector of filenames or filepaths and return TRUE or FALSE for each. It guesses that a file is text if it doesn't find any nul bytes in the first 2048 bytes of the file. This is an imperfect guess, but it is very likely that a binary/non-text file will have a nul byte near the beginning of the file. This might guess that a file that is not intended to be read in as text is a text file, but at least you will likely be able to read in the file as text without error. If the file is inaccessible, either because it is empty, you don't have permission to read it, it's a directory, or it doesn't exist, this function will return FALSE. If you pass anything that is not a character vector or a single column data.frame to the filepaths argument, this function will give an error.
