int handle_redirection

Handles redirections for a command.

Parses the command's arguments and sets the file descriptors for input, output, and error. If a file is not found, the function will print an error message and return -1.

Command arguments are modified in place to remove the redirection symbols and the file names. The file descriptors must be standard input/output/error. Otherwise, the function will print an error message and return -1.
