Describe the bug
Current Fee estimation logic:

Rather than logic being gasPrice * dataLen + executionPrice * gasUsed, logic should be:
gasPrice * (4*zeroDataBytes + 16*nonZeroDataBytes + nonCallDataL1GasOverhead) + executionPrice * gasUsed

1. dataPrice is currently the L1 gas price, not the price per byte of data. Non-zero data bytes cost 16 gas and zero data bytes cost 4 gas. We must iterate through the data, count # of zero, non-zero bytes, then calculate the cost.
2. There is currently a non-calldata per tx overhead for batch submission. The naive solution is to have this parameterizable in the config. Ideally we can query the L1 CTC to find a running average of the tx batch size and use that to parameterize this added cost.

Non calldata cost per tx (Assuming each tx has its own batch context):

Batches of 10 txs:
9145 gas per tx

Batches of 50 txs:
5253 gas per tx

Batches of 200 txs:
2661 gas per tx
