Garrett D'Amore 97c0480839 fixes #452 Lost a key event once when exiting or suspending in v2.2.1.
fixes #449 Lost keyboard input after suspend on Windows 10 PowerShell
fixes #148 Make tcell usable with any io.Reader and io.Writer

This introduces a new Tty interface so that applications can supply
their own implementation.  This should facilitate work for applications
that wish to provide e.g. a webasm version of the terminal, or that need
to use different kinds of file plumbing.
