CODEC-301: Reduce byte[] allocations by reusing buffers

* Reduces byte[] allocations from 280MB to <4MB when reading a 133MB base64 stream. Messured with JFR.
* Keep reusing inital buffer when decoding BaseN
* Attempt to fill up the user-provided buffer
    Previously we only filled up to a maximum of 8KB - encoding-overhead (e.g. 6KB for Base64) even if the provided
    buffer was bigger.
* Reuse hasData method for checking pos/readPos markers
