This PR improves InputStream assertions by introducing dedicated methods for binary and textual content comparison, allowing for more precise assertions and better charset handling.

Changes

• New Binary Comparison: Added hasSameBinaryContentAs(InputStream) for byte-to-byte comparison of two input streams.
• New Textual Comparison: Added hasSameTextualContentAs(InputStream, Charset) for character-based comparison, allowing users to specify the expected stream's charset.
• Charset Configuration: Added usingCharset(Charset) and usingCharset(String) to AbstractInputStreamAssert to define the charset for the actual InputStream being asserted.
• Deprecated hasSameContentAs(InputStream) in favor of the more explicit hasSameBinaryContentAs or hasSameTextualContentAs methods.
