[feature request] Add some Enum types

I'm using docx.v1.ListDocumentBlockRequest to get a docx.v1.Block. Then I'd like to write:

def get_text_block_by_type(block: docx.v1.Block) -> docx.v1.Text:
    name = FeishuBlockType(block.block_type).name
    value = block.__getattribute__(name)
    if isinstance(value, docx.v1.Text):
        return value
    else:
        return None

class FeishuBlockType(Enum):
    page = 1
    text = 2
    heading1 = 3
    heading2 = 4
    heading3 = 5
    heading4 = 6
    heading5 = 7
    heading6 = 8
    heading7 = 9
    heading8 = 10
    heading9 = 11
    bullet = 12
    ordered = 13
    code = 14
    quote = 15
    equation = 16
    todo = 17
    bitable = 18
    callout = 19
    chat_card = 20
    uml_diagram = 21
    divider = 22
    file = 23
    grid = 24
    grid_column = 25
    iframe = 26
    image = 27
    isv = 28
    mindnote = 29
    sheet = 30
    table = 31
    table_cell = 32
    view = 33
    quote_container = 34
    task = 35
    okr = 36
    okr_objective = 37
    okr_key_result = 38
    okr_progress = 39
    add_ons = 40
    jira_issue = 41
    wiki_catalog = 42

I belive it will be useful for developers to have the Enum types in lark_oapi , perticularly the fields like:

Relate to https://open.feishu.cn/document/server-docs/docs/docs/docx-v1/document/list

Start by inspecting the lark_oapi model definitions for docx.v1.Block and the related fields shown in the issue. Compare their numeric values and names with the Feishu Docx API documentation. Done means the requested Enum types are available for these fields and remain consistent with the documented values.
