Subject: [PATCH 2/5] Optimize .mat file loading performance
Improve the performance of reading MATLAB .mat files by optimizing the Inflate decompression method:
- Replace byte-by-byte reading/writing with efficient bulk operations
- Pre-allocate memory streams with estimated capacity to reduce reallocations
- Use Stream.CopyTo with optimized buffer size (80KB) for fast decompression
- Remove unnecessary bit masking operations
This optimization significantly reduces CPU cycles and memory operations when loading large .mat files, especially on systems with limited resources. The functional behavior remains unchanged.

+# CSMatIO WPF Demo Application
+
+This is a .NET 8.0 WPF demo application for the CSMatIO library, which provides functionality for reading and writing MATLAB MAT-files in C#.
+
+## Features
+
+- Read MAT-files and display their contents
+- Create MAT-files with various data types:
+ - Cell arrays
+ - Structures
+ - Character arrays
+ - Sparse arrays
+ - Numeric arrays (Double, Single, Int8, UInt8, Int16, UInt16, Int32, UInt32, Int64, UInt64)
+ - Imaginary matrices
+
+## Requirements
+
+- .NET 8.0 SDK or later
+- Windows operating system
+
+## Building and Running
+
+1. Open the solution in Visual Studio 2022 or later
+2. Build the solution
+3. Run the CSMatIOTestWPF project
+
+## Usage
+
+1. To read a MAT-file, click the "Read MAT-File" button and select a file
+2. To create a MAT-file:
+ - Select the data types you want to include
+ - Click the "Create MAT-File" button
+ - Choose a location to save the file
+
+The output window will display information about the operations performed.
