[Joe Martin]

This version of Angelia firmware adds an additional CW keying option by using digital input IO4 on Angelia; pin 9 on J16 header and pin 9 on the rear panel accessory jack on ANAN-100D, to allow CW straight keying when in iambic CW mode.  This change permits the use of AUTO TUNE feature of some external PAs and/or straight key use simultaneously with an iambic key paddle.  The input line is debounced, KEY is low (to ground), UNKEY is high via a pull up resistor on the Angelia board.  

The user should ensure that the max external voltage from the keying source should is no more than 3.3V DC when unkeyed; no external voltage is necessary.
