Add the ability to specify which pin to pulse when retrying entry into

programming mode.  Use 'retry_pulse' in the per-part specification
that can currently take values of 'reset' or 'sck', the default being
'sck' which preserves the previous behaviour.  Some newer parts
indicate that /RESET should be pulsed, while older parts say to pulse
SCK.
