** hasak text keyer component.
**
** I've adopted the compact code representation and the winkey convention
** of a prefix operator to form prosigns by concatenation, but I'm feeling
** a little queasy about corner cases.
**
** The morse table has moved into the NRPN array, so it can be augmented as
** required.  It covers the 64 characters from ! to `, though many are undefined
** by default.
