Addresses #320, #236 * Adding External printer * Made ExternalPrinter as an optional feature. Clippy is happy, test pass, docs added. * ExternalPrinter: prints multiple messages if available, more on error-handling. * Bug(s) fixed. Prints messages. Working example in examples folder. Code formatted, clippyed, tests pass. * Generic ExternalPrinter<T> where T: Display. * Fixed: Works with buffers larger than a line. * Fixed: Works with buffers larger than a line, refactored. * Different approach, seems to look like what is expected. Gives the "illusion" of one line being entered. Needs more testing, could have some off by one errors ;) Co-authored-by: Gregor Engberding <gregor@meinkopter.de>
