10MHz crystal support

According to https://github.com/andreasberg/CAN_BUS_Shield there are also boards using a 10MHz crystal. Shouldn't be hard to add.

Handling the hardware reset pin

Currently the library does not perform any handling for pins that might be connected to the devices hardware reset line, is this intentional?

Boards such as the CAN SPI Click connect up the hardware reset line which needs to be actively pulled high to remove the device from reset.

Currently I modified the library to optionally perform a hardware reset (holding the reset line low for a period of time before pulling it high again) as part of library initialisation. Default behaviour, if no reset pin is defined, is the same as the unmodified libraries behaviour.

I'm happy to raise a pull request providing this functionality if desired but wasn't sure whether this behaviour was deliberately not part of the libraries functionality.

Add examples

Add examples for GPIO

TX0RTS,TX1RTS and TX2RTS generic digital input mode

TX0RTS,TX1RTS and TX2RTS allow for use as general purpose digital input with 100kΩ pull-up to Vdd

Update examples

Examples do not work using the current constructors
