move flashbots/eth-sparse-mpt to a workspace crate (#248)

## 📝 Summary

Move all the code from flashbots/eth-sparse-mpt to this repo to make
reth / alloy upgrades easier.

<!--- A general summary of your changes -->

closes #210

## 💡 Motivation and Context

eth-sparse-mpt heavily depends on reth and alloy and this will make
updates of the rbuilder dependencies easier.

---

## ✅ I have completed the following steps:

* [x] Run `make lint`
* [x] Run `make test`
* [x] Added tests (if applicable)

+This library is useful when you need to calculate Ethereum root hash many times on top of the same parent block using reth database.
+
+To use this, for each parent block:
+* create `SparseTrieSharedCache`
+* call `calculate_root_hash_with_sparse_trie` with the given cache, reth db view and execution outcome.
+
+
+### Speedup example.
+
+* block 20821340
+* machine with 64 cores, Samsung 980Pro SSD
+
+We calculate root hash of some specific blocks in a loop using the same changes.
+This implemenation caches only disk access, all storage and main trie hashes are calculated fully on each iteration.
+
+```
+reth parallel root hash:
+
+first iteraton : 220 ms
+next iterations: 140 ms (median, stable)
+
+eth-sparse-mpt:
+
+first iteraton : 225 ms
+next iterations: 5.1 ms (median, stable)
