feat: higher priority fee when late

[segfault-magnet]

closes: #180

Analyzed our worst offenders and it seems there is nothing else to do but bump the priority fee more as we get more desperate.

For context:
The priority fee percentage mentioned in the PR is explained nicely here:

 * @param args.percentiles - A set of numbers between 1 and 100 which will dictate how
 * `priorityFeesByPercentile` in each returned block will be formed. When Ethereum runs the
 * `eth_feeHistory` method, for each block it is considering, it will first sort all transactions by
 * the priority fee. It will then go through each transaction and add the total amount of gas paid
 * for that transaction to a bucket which maxes out at the total gas used for the whole block. As
 * the bucket fills, it will cross percentages which correspond to the percentiles specified here,
 * and the priority fees of the first transactions which cause it to reach those percentages will be
 * recorded. Hence, `priorityFeesByPercentile` represents the priority fees of transactions at key
 * gas used contribution levels, where earlier levels have smaller contributions and later levels
 * have higher contributions.

The default priority fee estimator in Alloy requests the 20th percentile for the last 10 blocks and calculates the median max priority fee per gas from that.

This PR makes the percentile configurable by setting the min and max value. The percentile will increase between those as we get more and more behind reaching the max percentile on max_l2_blocks_behind.

The base branch was changed.
