improve CZI-write (#10)

* Enhance CziWriter::Close for C-dimension display settings

Updated the `Close` method to handle C-dimension statistics.
If the C-dimension is valid, default display settings are applied
to each channel to prevent display issues in certain ZEN versions.
The metadata builder is utilized to write these settings before
retrieving the XML for metadata writing.

* Bump patch version and enhance CZI handling tests

Updated `CMakeLists.txt` to increment the patch version of the `MEXLIBCZI` library from 4 to 5.
Refactored the `Close()` method in `CziWriter.cpp` to utilize a `unique_ptr` for better memory management.
Added a new test function in `TestMEXlib_Write.m` to validate multi-channel CZI file creation and properties.

* Update documentation for writer object's subblock

Added details on available pixel types for argument #4 and options for argument #6 in the writer object's subblock documentation.

Add build for ubuntu22 (#9)

* adding build for Ubuntu22 and Octave6.4.0
