Extends support for actively driving I2C via GPIO push-pull instead of passively through open-drains. Useful for chips not having open-drain support in the GPIO peripheral. Defaults to open-drain, selectable by SW_I2C_USE_OPENDRAIN

SW_I2C_USE_OPENDRAINCompared to the default I2C fallback driver, this one also has further delays added to conform with the I2C protocol where appropriate, should be more stable.
Tested extensively in both open-drain and push-pull config. Both standard and fast mode I2C is achievable reliably
