Breaking Changes

Renamed all .rawTransaction properties to .raw_transaction (Web3.py v7 naming).
Completely refactored middleware for Web3.py v7: now a class-based middleware using wrap_make_request.
Overhauled FlashbotProvider:
- Replaced internal Web3 HTTP utils with requests.post.
- Removed deprecated imports from eth_account._utils.

Added

Official compatibility with Web3.py v7 (7.x series).
New helper get_transaction_type() to detect legacy, access list, and EIP-1559 tx types.
Expanded tests covering _parse_signed_tx for legacy, EIP-2930 (type=1), and EIP-1559 (type=2) transactions.

Fixed

Ensured numeric RLP fields (bytes) are converted to int.
Added recovery of chainId for legacy transactions signed under EIP-155.
Updated examples (examples/simple.py) to use .raw_transaction and new middleware/provider APIs.
