Update version

Adjust the 1/2 bit time to match the number of extra cycles in the actual
PIO loop.

Throw out the entire start bit, which results in sampling the data at the
midpoint and not the starting time of a bit (which was causing random
failures on read data).

Tested at 300bps all the way to 2,000,000bps using a loopback connection.

Fixes #360

+============
+
+The Raspberry Pi Pico has the ability to set the current that a pin (actually the pad associated with it) is capable of supplying. The current can be set to values of 2mA, 4mA, 8mA and 12mA. By default, on a reset, the setting is 4mA. A `pinMode(x, OUTPUT)`, where `x` is the pin number, is also the default setting. 4 settings have been added for use with `pinMode`: `OUTPUT_2MA`, `OUTPUT_4MA`, which has the same behavior as `OUTPUT`, `OUTPUT_8MA` and `OUTPUT_12MA`.
