Readme Usage Examples No Longer Point To Existing Files

[tateexon]

The example currently shown in the README.md:

$ poetry install

# connecting to Injective Exchange API
# and listening for new orders from a specific spot market
$ poetry run python examples/exchange_client/spot_exchange_rpc/8_StreamOrders.py

# sending a msg with bank transfer
# signs and posts a transaction to the Injective Chain
$ poetry run python examples/chain_client/1_MsgSend.py

The issue being examples/exchange_client/spot_exchange_rpc/8_StreamOrders.py and examples/chain_client/1_MsgSend.py no longer exist.

Expected:
The files shown in the examples are valid files and running them will work.

Actual:
The files shown in the examples are no longer present.
