Issue: Implement starknet_getBlockTransactionCount RPC Call

Description:
The starknet_getBlockTransactionCount RPC call has been implemented but requires further testing and verification against the entire state. This RPC call retrieves the number of transactions in a block given a block id.

Parameters:

• block_id: The hash of the requested block, or number (height) of the requested block, or a block tag. This parameter is required.

Expected Result:
The number of transactions in the designated block.

Potential Errors:

• BLOCK_NOT_FOUND: The specified block could not be found.

Testing:
Initial testings can be found here. However, these should not be considered complete and improvements are welcome.

Resources:

• Alchemy RPC API Endpoint Documentation
• Starknet API OpenRPC Spec
