v3.3.2

features:

• use optimal read buffer size in SerialInputOutputManagerto reduce latency for FTDI and CH34x
• getReadEndpoint() and getWriteEndpoint() methods moved to UsbSerialPort interface

fixes:

• read w/o timeout now throws exception on connection lost or buffer to small (when using SerialInputOutputManager the exception was already thrown before this change, because the next read failed)
• Use monotonic clock for timeout calculation, to avoid issues when time is adjusted
