77813c8032 Rename GPIO_CONF_PUSH_PULL to GPIO_CONF_OPEN_DRAIN 
Seems I got the functionality of this bit inverted when
initially testing.

In testing it also seems open drain mode is ignored on some pins, which
still source current. Needs more investigation though (may be pullups
internal to the ESP modules or set by default in software.)

Relates to #45

1b0124cf05 Timer FRC1 & FRC2 registers 
Mostly determined from reverse engineering and poking around.

Includes first "experiments" program with random bits and pieces for
poking at registers, may be useful to keep in source control but not
useful for writing actual programs.
