Describe the feature @dphilipson implemented an (Alchemy internal) version of this here: https://github.com/OMGWINNING/bestimate-gas

The Stackup team also described a similar approach here: https://www.stackup.sh/blog/estimating-callgaslimit-for-useroperations

As this doesn't cover all cases (when using GAS opcode), we still need to keep the binary search fallback. This may have some performance improvements (especially if a native tracer is used) during gas estimation.
