verkle proof deserialization (#61)

* use proof serialization

* remove cruft

* save current state

* fix most issues up to this point

* fix remaining build issues

* update the go.mod to use the right branch

* remove custom-defined set type

* update go-verkle to get merged PRs

* extract key, value data from proof

* only activate precomp calculations if this is a verkle chain
