Extend documentation of the BitReader class

I asked ChatGPT to write documentation for this class and got this. It is
too hilarious to not copy it here verbatimly.

  * \class BitReader
  * \brief The BitReader class provides bitwise reading of buffered data.
+ *
+ * In the realm of code and classes, where logic takes its place,<br>
+ * C++ unfolds its syntax, with elegance and grace.<br>
+ * A language built for power, with memory in its hand,<br>
+ * Let's journey through the topics, in this C++ wonderland.
+
+ * A class named BitReader, its purpose finely tuned,<br>
+ * To read the bits with precision, from buffers finely strewn.<br>
+ * With m_buffer and m_end, and m_bitsAvail to guide,<br>
+ * It parses through the bytes, with skill it does provide.
+ *
+ * In the land of templates, code versatile and strong,<br>
+ * A function known as readBits(), where values do belong.<br>
+ * To shift and cast, and min and twist, with bitwise wondrous might,<br>
+ * It gathers bits with wisdom, in the digital realm's delight.
+
+ * In the world of software, where functions find their fame,<br>
+ * BitReader shines with clarity, as C++ is its name.<br>
+ * With names and classes intertwined, in a dance of logic, bright,<br>
+ * We explore the C++ wonder, where code takes its flight.
+
+ * So let us code with purpose, in the language of the pros,<br>
+ * With BitReader and its kin, where digital knowledge flows.<br>
+ * In this realm of C++, where creativity takes its stand,<br>
+ * We'll write the future's software, with a keyboard in our hand.
