Cleanup: OPC UA is written as "OPC UA" (not "OPC/UA") (#21)

Note: OPC UA is the acronym for OPC Unified Architecture, with OPC referring to the Open Platform Communications (Foundation).

-This library provides an implementation of [OPC/UA](https://en.wikipedia.org/wiki/OPC_Unified_Architecture) by porting the Fraunhofer [`open62541`](https://github.com/open62541/open62541) for the Arduino [Opta](https://www.arduino.cc/pro/hardware-arduino-opta/) `microPLC` family.

 Furthermore, the library supports automatic detection, configuration and exposure of up to two Arduino Opta Expansion Boards (i.e. Digital Expansion w/ mechanical relays [`D1608E`](https://store.arduino.cc/products/opta-ext-d1608e), Digital Expansion w/ solid-state relays [`D1608S`](https://store.arduino.cc/products/opta-ext-d1608e), Analog Expansion [`A0602`](https://store.arduino.cc/products/opta-ext-a0602)) via OPC UA.
