* feat: pseudo-generic extra payloads in `params.ChainConfig` and `params.Rules` * feat: `params.ExtraPayloadGetter` for end-user type safety * refactor: payloads only available through `params.ExtraPayloadGetter` * chore: make `libevm/examples/extraparams` a `params` testable example * doc: `libevm/pseudo` package comments and improved readability * doc: `params.*Extra*` comments and improved readability * doc: `params.ExtraPayloadGetter` comments and improved readability * doc: `params/config.libevm_test.go` comments and improved readability * refactor: simplify `params.ChainConfig.UnmarshalJSON()` * refactor: abstract new/nil-pointer creation into `pseudo.Constructor`s * feat: precompile override via `params.Extras` hooks * doc: flesh out `PrecompileOverride()` in example * doc: complete commentary and improve readability * refactor: `ChainConfig.Hooks()` + `Rules` equivalent * chore: rename precompiles test file in keeping with geth equivalent * feat: stateful precompiles + allowlist hooks The allowlist hooks are included in this commit because they allow for the same functionality as stateful precompiles in `ava-labs/coreth` and `ava-labs/subnet-evm`. * fix: `StateTransition.canExecuteTransaction()` used `msg.From` instead of `To` * test: `params.RulesHooks.CanCreateContract` integration * test: `params.RulesHooks.CanExecuteTransaction` integration * test: `vm.NewStatefulPrecompile()` integration * refactor: simplify test of `CanCreateContract` * refactor: abstract generation of random `Address`/`Hash` values * doc: full documentation + readability refactoring/renaming * fix: remove circular dependency in tests
