In order to make the most commonly available version fit, you can strip of the plastics from the power pins and carefully bend both GND and Vdd pins in a Z-shape so they will fit in the adjacent pin hole.

This catch-22 situation can be resolved by adding a simple diode from GPIO-0 to the "3.3V" pad. (the 'line' on the diode towards the "3.3V" pad)

In this test setup, a basic 1N4001 is used, which has a voltage drop of about 0.5V.

Another option is to use a germanium diode like the 1N4148, which does have a voltage drop of 0.3V.
