Pull request overview

This PR fixes a bug in the Tuya integration's BitmapTypeInformation parsing. The issue occurred when parsing JSON data containing bitmap type information with multiple fields - the old code attempted to unpack all JSON keys as constructor arguments, but the BitmapTypeInformation dataclass only accepts a label field, causing a TypeError when additional keys like maxlen were present.

Key Changes

• Fixed BitmapTypeInformation._from_json to explicitly extract only the label field instead of unpacking the entire parsed dictionary
• Added type cast for improved type checking consistency with other type information classes
• Added test fixture for automatic cat litter box device (msp_5t7esmqqh92ssbe5.json) that includes bitmap type data with multiple fields
