Add the ability to pass default signal handler for SIGWINCH in BBProgress
because with multiple instace of BBProgress the original signal handler
set by TerminalFilter (sigwinch_handle) is lost.
This is a fix for stack trace due to multiple async calls of ProgressBar
_handle_resize (ioctl to terminal fd), see:
NOTE: Executing SetScene Tasks
Fatal Python error: Cannot recover from stack overflow.
