text-splitters[patch]: fix MarkdownHeaderTextSplitter fails to parse headers with non-printable characters (#20645)
Description: MarkdownHeaderTextSplitter Fails to Parse Headers with
non-printable characters. more #20643

The following is the official test case. Just replacing `# Foo\n\n` with
`\ufeff# Foo\n\n` will cause the test case to fail.

chunk metadata is empty

```python
def test_md_header_text_splitter_1() -> None:
    """Test markdown splitter by header: Case 1."""

    markdown_document = (
        "\ufeff# Foo\n\n"
        "    ## Bar\n\n"
        "Hi this is Jim\n\n"
        "Hi this is Joe\n\n"
        " ## Baz\n\n"
        " Hi this is Molly"
    )
    headers_to_split_on = [
        ("#", "Header 1"),
        ("##", "Header 2"),
    ]
    markdown_splitter = MarkdownHeaderTextSplitter(
        headers_to_split_on=headers_to_split_on,
    )
    output = markdown_splitter.split_text(markdown_document)
    expected_output = [
        Document(
            page_content="Hi this is Jim  \nHi this is Joe",
            metadata={"Header 1": "Foo", "Header 2": "Bar"},
        ),
        Document(
            page_content="Hi this is Molly",
            metadata={"Header 1": "Foo", "Header 2": "Baz"},
        ),
    ]
    assert output == expected_output
```

text-splitters[minor]: Adding a new section aware splitter to langchain (#16526)
- **Description:** the layout of html pages can be variant based on the
bootstrap framework or the styles of the pages. So we need to have a
splitter to transform the html tags to a proper layout and then split
the html content based on the provided list of tags to determine its
html sections. We are using BS4 library along with xslt structure to
split the html content using an section aware approach.
  - **Dependencies:** No new dependencies
  - **Twitter handle:** @m_setayesh
